CVE-2026-97229 is a maximum-severity GitLab flaw in the CI/CD Regular Expression Compiler, caused by an integer overflow, that lets unauthenticated attackers run code via a crafted regular expression. CISA added it to the KEV Catalog and ordered federal agencies to patch under BOD 26-04. GitLab fixed it in CE/EE 19.4.2, 19.3.5 and 19.2.8, and Shadowserver tracks about 2,800 exposed CE instances.

CVE-2026-97229 is a CVSS 10 code execution flaw in Onigmo, Ruby's regular expression engine, reachable through crafted CI/CD configuration in GitLab. Attackers used it against Alpine Linux's GitLab on 20 and 21 October 2026 and failed; Alpine rebuilt the instance and found no tampering with aports or packages. Self-managed installs with their own Ruby need Ruby 3.3.13, 3.4.12 or 4.0.9, not just GitLab 19.3.6. CISA added it to KEV.

ADLC metrics is an Endor Labs guide to measuring security in the agentic development lifecycle, where AI coding agents write much of the code. It defines formulas across five categories: AI supply chain visibility, agent action security, agent-generated code, package risk and developer flow. It argues for normalizing findings per merged change, tracking pre-execution blocks, and building a six-to-eight metric scorecard.

The ADLC maturity model is a proposed five-stage framework from Endor Labs for scoring security controls over coding agents, from unmanaged experimentation to continuous verification. Each stage has requirements on two tracks, agent actions (shell commands, MCP calls, package installs) and agent output (code, dependencies, secrets). It sets stage 3 at deterministic hooks that block actions, gives evidence-based assessment questions, and lists traps such as relying on prompt-level rules.

It frames the "forge later" threat and maps CNSA 2.0 (ML-DSA-87 only for NSS) and EU CRA deadlines to actions.

JFrog proposes Agentic Process Evidence, an open protocol that records AI coding agent sessions (harness, model ID, tool calls, MCP use, prompts, owner, human reviewer) as signed in-toto/DSSE, SLSA-compatible attestations bound to commits, artifacts and releases. Policy-as-code gates can then block releases that used unapproved LLMs or MCP tools, or that lack an accountable human. It maps the approach to EU AI Act Articles 12/14, OWASP AISVS and ISO/IEC 42001, and includes example session-log and evidence JSON. The post also promotes JFrog AppTrust's Prompt to Release Traceability.

Vendor-authored guide that defines a software supply chain as developers, code, dependencies, AI models, containers and CI/CD pipelines. It walks through program components: OSS governance, SAST vs reachability-based SCA, AI model security, SBOM/VEX (NTIA minimum elements, SPDX vs CycloneDX), secrets scanning, CI/CD hardening, and signing/attestation with Cosign/Sigstore. It cites figures such as 95% of vulnerabilities sitting in transitive dependencies and only 1% of SBOMs being fully NTIA-conformant. Each section closes with an Endor Labs product pitch, so treat the framing as vendor-flavoured. The fetched text was truncated, so the final attestation/provenance section was not seen.

Endor Labs breaks down the May 11, 2026 compromise of 42 @tanstack/* npm packages (84 malicious versions) that carried valid SLSA provenance. The attacker chained a pull_request_target "Pwn Request", GitHub Actions cache poisoning across the fork/base boundary, and OIDC token extraction from Runner.Worker memory, then published directly to npm without stealing any credential. It explains why 2FA, trusted publishing, provenance and branch protection all failed, and lists mitigations: split pull_request_target workflows, treat the cache as untrusted, scope id-token: write to a publish job, pin actions to SHAs, require environment approval, use egress allowlists.

StepSecurity recaps a 48-hour (May 18-19, 2026) software supply-chain attack wave that hit every pipeline layer at once: the Nx Console VS Code extension (2.2M installs) stealing tokens from GitHub/npm/AWS/1Password, the trusted GitHub Action actions-cool/issues-helper hijacked via tag replacement, a trojanized Microsoft durabletask PyPI package pulled within a 35-minute discovery window, a self-replicating Shai-Hulud npm worm, and GitHub's own disclosure that ~3,800 internal source repos were exfiltrated. The piece argues traditional SCA/SAST/EDR/CNAPP tooling missed all of it because none monitor CI/CD runner runtime behavior (e.g., attackers reading /proc/pid/mem to extract secrets) or developer-machine IDE extensions, and ties the incidents to StepSecurity's Harden Runner, Dev Machine Guard, Compromised Actions Policy and Secure Registry controls.

StepSecurity's investigation of @subql/common@5.8.3, a malicious npm release in the SubQuery Web3 indexing framework's monorepo, found a heavily obfuscated postinstall/import-time payload (base64+XOR+gzip inside a function constructed via Function()) that spawns a detached worker to steal credentials (.npmrc, .env, AWS, SSH, kubeconfig, Vault, cloud secrets), read GitHub Actions runner memory for CI secrets, inject a camouflaged "Run Copilot" GitHub Actions workflow to exfiltrate repo secrets, and provide a remote shell/PTY over an encrypted channel to ci-artifacts.dev. The release was published via a compromised build pipeline: a workflow modification swapped the real build output for an externally downloaded, unsigned tarball from that same C2 domain immediately before publish, and the authors provide IOCs and remediation steps (credential rotation, host isolation, domain blocking).

Wiz Research examined the source repositories and CI/CD pipelines behind 1,500 popular Helm charts on Artifact Hub (mapping to 814 unique GitHub repos) and found 61 repos (7.5%) with confirmed supply-chain risk, including 20 charts with CI/CD workflow weaknesses and 25 depending on unmaintained/archived upstream projects. Two disclosed findings illustrate the risk classes: KubeView's go.mod referenced a Go module under a GitHub username that didn't exist, making it hijackable by anyone who registered the name, and Meilisearch's Helm chart repo had a GitHub Actions workflow triggered by PR comments that injected the commenter's branch name into a shell command while skipping author-association checks, letting any GitHub user run commands with a bot token that had push access.

UnderSpecBench is a benchmark of 69 task families (2,208 prompt variants) grounded in real incidents and CVEs that tests whether coding agents (Claude Code, Codex, OpenCode) safely handle underspecified DevOps instructions rather than guessing at intent, target, or blast radius. Using deterministic side-effect oracles, the study finds 55.8–67.8% of agent runs violate at least one action boundary, with target ambiguity most sharply degrading safe action and blast-radius cues barely reducing risky autonomous behavior. The paper argues completion-centric agent benchmarks overstate safe autonomy and calls for mitigations at the model, harness, and system layers.

This arXiv paper proposes a blockchain-anchored agentic AI framework for securing the software development lifecycle: specialized LLM-backed agents handle source integrity, SBOM/dependency analysis, CI configuration auditing, artifact verification, and runtime policy evaluation, each producing a cryptographically signed attestation recorded on a permissioned blockchain via smart contracts (agent registry, immutable attestation log, release-policy module). Agent-to-agent and agent-to-blockchain communication is secured through a consortium-operated certificate authority, and a sequence flow illustrates a source-code security agent anchoring its attestation on-chain to trigger an allow/block deployment decision. It's a conceptual architecture paper rather than an evaluated deployment, aiming to give decentralized, tamper-resistant provenance for agentic AI monitoring the software supply chain.

StepSecurity documents Megalodon, a May 2026 campaign that injected backdoored GitHub Actions workflow files named SysDiag or Optimize-Build directly into 5,500+ public repositories in a six-hour window via direct Poisoned Pipeline Execution (d-PPE), exploiting weak branch protection. The base64-encoded bash payload harvests AWS/GCP/Azure credentials, SSH keys, Kubernetes/npm/Docker configs, GitHub OIDC tokens, and grep-matched secrets from the workspace, exfiltrating everything via HTTPS POST to a hardcoded C2 IP; the npm package @tiledesk/tiledesk-server was among the confirmed poisoned downstream targets.

StepSecurity discovered that all 53 tags of the popular actions-cool/issues-helper GitHub Action (and all 15 tags of actions-cool/maintain-one-comment) were re-pointed to dangling imposter commits containing malicious code. The payload downloads the Bun runtime, reads Runner.Worker process memory to harvest decrypted CI/CD secrets, and exfiltrates them via HTTPS to t.m-kosche.com — meaning any workflow referencing the actions by tag (rather than a pinned commit SHA) pulls the malicious code on its next run.

The action compares one-second-precision pushed_at and comment created_at timestamps to detect post-authorization pushes, but a strict greater-than check lets an attacker push a malicious commit in the same second as an authorized "please update snapshots" comment, causing the action to check out and later execute attacker-controlled code (including a local composite action and jlpm-driven package scripts) with the workflow's GITHUB_TOKEN (contents: write, pull-requests: write) in the jupyter/notebook repository. The issue was fixed in v1.0.0 and is a variant of the "pwn request" class of GitHub Actions vulnerabilities.

It cites hard data — GitGuardian's 2026 report found 28.65M new hardcoded secrets on public GitHub in 2025 and a 3.2% secret-leak rate on Claude Code-assisted commits vs 1.5% baseline, Lakera found credentials in 33 .claude/settings.local.json files across 30 packages, and Wiz found AI-related secrets among the most common validated leaked credential types — then lays out a layered defense (pre-commit/IDE/CI/CD/full git-history scanning, active credential validation, secure prompting) and an incident-response order of operations (rotate, investigate, purge history, revoke, re-scan).

StepSecurity's Harden-Runner GitHub Action v2.21.0 adds a denied-endpoints input, letting teams block specific egress destinations (domains, wildcards, bare IPs) from CI jobs while leaving everything else reachable — a lighter-weight alternative to allow lists that don't require full enumeration of a job's needs. The piece details how deny-list entries differ from allow-list ones (no per-port scoping), covers the flagship use case of forcing package installs through StepSecurity's Secure Registry proxy by denying direct access to registries like PyPI and Go module hosts, and explains that Harden-Runner's separately maintained Global Block List (built from SOC threat intel, e.g. the Megalodon credential-exfiltration campaign) is distinct from and complements user-managed deny lists. It also candidly notes the deny list's blind spot: campaigns like Shai-Hulud 2.0 that exfiltrate via github.com itself can't be stopped by a deny list, requiring allow-list enforcement instead.

The post frames the feature around CVE-2025-8217, where a threat actor exfiltrated GitHub tokens by dumping CodeBuild build-environment memory via a malicious pull request to compromise the AWS Toolkit for Visual Studio Code and AWS SDK for .NET repos, and notes that CodeBuild runners additionally expose an assumed IAM service role and VPC network reachability that GitHub-hosted runners don't have. Harden-Runner correlates outbound network calls, file writes, and process executions to the workflow step that triggered them and unifies detection across GitHub-hosted, self-hosted, ARC, and CodeBuild-hosted runner fleets.

It chronicles the full attack progression from credential-phishing (Debug/Chalk, Axios) through Pwn Request-driven CI compromise (S1ngularity, Shai-Hulud 2.0) to the Mini Shai-Hulud II/TanStack attack, which poisoned the GitHub Actions cache to extract a live OIDC token from runner memory and publish packages with valid SLSA Build Level 3 provenance — proving Trusted Publishing itself can be turned into the attack vector rather than just bypassed.

Endor Labs analyzes why a string of npm supply-chain campaigns — Shai-Hulud 2.0 (Nov 2025, 796 packages backdoored) and an April 2026 SAP-ecosystem attack on mbt, @cap-js/db-service, @cap-js/sqlite and @cap-js/postgres — all use the same second stage: a preinstall script that downloads the Bun JavaScript runtime to run an obfuscated credential stealer. Bun is attractive to attackers because it's a userland, statically-linked binary with a different process name than node, bypasses Node's --require/NODE_OPTIONS instrumentation hooks, and ships built-in shell/decompression/HTTP primitives (Bun.$, Bun.gunzipSync) that avoid the suspicious imports scanners look for. The piece also notes CVE-2026-24910, a trusted-dependency spoofing flaw in Bun's package manager, and recommends prioritized controls: disable npm lifecycle scripts (ignore-scripts=true) with an auditable allowlist, enforce a minimum release age/cooldown on dependencies, block known-malicious versions pre-install, eliminate long-lived npm/cloud tokens, and detect on process lineage rather than binary name.

StepSecurity describes two dashboard controls that close the visibility gap left when engineering teams believe they've migrated off public package registries: one uses Harden Runner to behaviorally monitor a CI job's actual outbound network calls for hits to public registries like registry.npmjs.org or pypi.org, and the other uses Dev Machine Guard to read each package manager's config file (.npmrc, pip.conf) on every developer machine to report its effective registry. It ties this to 2026 incidents — malicious axios versions on npm, a credential stealer hidden in two litellm PyPI releases, and a republished @bitwarden/cli that harvested SSH keys and GitHub tokens to inject malicious CI workflows — arguing developer machines, not just CI, are the entry point attackers use. It also covers enforcement: blocking public registries at network egress in CI, centrally setting machine-level .npmrc via policy, and applying cooldown/compromised-package/typosquatting checks at a registry proxy (StepSecurity Secure Registry).

StepSecurity reconstructs how a malicious version of XanaduAI's mrmustard quantum-photonics library (0.7.4) reached PyPI: an attacker compromised a maintainer's GitHub account, used a throwaway workflow to exfiltrate the project's PyPI and Codecov tokens via webhook.site, then published a poisoned tarball directly (the malicious code never touched the git source tree). On import, the payload evades CI/container sandboxes, then steals SSH keys, AWS/Kubernetes credentials, and HPC/GPU environment data, XOR-obfuscates it, and beacons to metrics.femboy.energy before installing three persistence mechanisms (cron job, Python .pth hook, shell rc hook).

Socket researchers traced malicious dev versions of ten Packagist packages owned by developer dinushchathurya back to compromised GitHub repositories containing 55-62 malicious GitHub Actions workflow files each. The workflows execute on GitHub-hosted Ubuntu runners on every push, download an architecture-matched Linux payload from C2 server 43.228.157.68, and run an internet scanner (`ipscan --exploit CVE-2026-41940`) that exploits an authentication bypass in cPanel/WHM and harvests cloud, database, SSH, and source-control credentials, exfiltrating results via heartbeat/results HTTP endpoints and DNSHook callbacks. GitHub code search for the campaign's unique markers returned 6,100-16,000 matching workflow files across unrelated repositories, indicating the abuse extends far beyond the one compromised maintainer and effectively weaponizes GitHub Actions as free, disposable attack infrastructure.

Aikido argues that the reflexive SCA-tool advice to 'just upgrade' to fix a CVE breaks down in three cases: no fixed version exists (e.g. the deprecated Node.js 'request' package's SSRF advisory), the fix hasn't shipped yet (lodash CVEs affecting all versions up to 4.17.23), or the fix ships with breaking changes (Node.js CVE-2026-48937, which bundled a fix with removal of HTTP/2 priority signaling). It also cites the chalk/debug npm maintainer-account compromise as evidence that blind auto-upgrading can pull in malware, and pitches backporting isolated fixes to already-deployed versions (via Aikido Libraries) as the alternative to upgrade-or-freeze.

npm v12 is now generally available, disabling preinstall/install/postinstall lifecycle scripts, the implicit node-gyp rebuild triggered by binding.gyp, git dependency resolution, and remote URL dependency resolution by default, all of which required explicit opt-in via allowScripts, --allow-git, and --allow-remote. The release also begins phasing out granular access tokens configured to bypass 2FA, first restricting their account/org actions (~Aug 2026) and later removing their ability to publish directly (~Jan 2027), pushing teams toward trusted publishing (OIDC) or staged-publish-with-2FA-approval workflows instead. The changes respond to a year of install-time supply-chain worms (Shai-Hulud, Miasma/Phantom Gyp) that exploited default script execution and binding.gyp-based implicit builds to evade scanners.

GitHub released actions/checkout v7, which by default blocks checkouts of untrusted fork pull request code (via refs/pull/*/merge, fork head SHA, or fork repository) when running under pull_request_target or workflow_run-from-pull-request events, closing a long-known "pwn request" vector that grants attacker-controlled code access to base-repo secrets and GITHUB_TOKEN. The protection auto-applies to workflows pinned to floating major tags and backports to all supported versions on July 16, 2026; an allow-unsafe-pr-checkout opt-out flag is provided for workflows that intentionally need the old behavior. The article ties the change to real incidents (Nx supply chain attack, Shai-Hulud second wave via PostHog, and the TanStack compromise combining pwn request with cache poisoning and OIDC token extraction) and notes the fix only covers actions/checkout itself, not git/gh CLI or other checkout mechanisms.

SkillsGuard is a zero-dependency static security scanner for AI agent skill packages (SKILL.md files and bundled scripts) that detects prompt injection, exfiltration, obfuscated payloads, persistence, and privilege escalation before an agent reads or executes them. It recursively decodes base64/hex/URL-encoded blobs to catch hidden attacks like a base64-wrapped reverse shell, computes a 0-100 risk score, and integrates into CI (SARIF/JSON output), git pre-commit hooks, and Claude via an MCP server (scan_skill tool) or a free hosted Cloudflare Workers API. The README also situates it against competing agent-skill scanners (NVIDIA, Cisco, Snyk, Mondoo, SkillSpector, SkillScan), noting it's the only one requiring no account/API/LLM dependency versus SkillSpector's LLM-augmented semantic analysis backed by a study of 42,447 scanned skills.

VICE is an open-source (MIT) Node.js security auditing CLI with two modes: a remote black-box scan that crawls a target with a headless browser across 15-16 security modules (headers, TLS, Supabase access controls, subdomains, storage buckets, WebSockets), and a local white-box audit that scans source code for secrets, .env exposure, npm vulnerabilities, missing Supabase RLS policies, SQL injection and XSS. It ships as a GitHub Action that posts PR comments with a security score, uploads SARIF findings to GitHub Code Scanning, gates merges on a minimum score, and maintains a live README badge. Version 3.4.0 adds an AI/RAG security module for testing chat/agent API endpoints for access control, prompt injection, retrieval isolation, and tool-security issues.

StepSecurity's forensic analysis of the June 5, 2026 Miasma worm incident, in which a compromised contributor account pushed a malicious commit to Microsoft's Azure/durabletask repository planting five files (.claude/settings.json, .gemini/settings.json, .cursor/rules/setup.mdc, .vscode/tasks.json, and a 4.6MB obfuscated .github/setup.js payload) that trigger credential-harvesting code execution the moment the repo is opened in Claude Code, Gemini CLI, Cursor, or VS Code — no package install or code run required. GitHub's automated abuse detection disabled 73 Microsoft repositories in a 105-second sweep, including Azure/functions-action, breaking CI/CD pipelines across GitHub Actions users relying on the mutable @v1 tag.

Socket's AI scanner found a coordinated supply chain campaign in which 8 Packagist (PHP/Composer) packages had their upstream GitHub repos modified to add a malicious postinstall hook — placed in package.json rather than composer.json — that downloads a binary (gvfsd-network) from an attacker GitHub Releases URL to /tmp/.sshd, disables TLS verification, and runs it in the background. The same payload was also found injected into GitHub Actions workflow files (as a step named "Dependency Cache Sync") in forked repos, and a GitHub code search for the attacker account parikhpreyash4 surfaced hundreds of additional references across Node.js projects. Highest real-world risk is concentrated in Laravel starter kits devdojo/wave (~6,400 stars) and devdojo/genesis (~9,100 Packagist installs), since starter-kit repos become the project root where npm install triggers the hook directly.

Individual users can now be added as bypass actors on repository-level rulesets through the UI, REST API and GraphQL, so a dedicated team or role is no longer needed for a single person or service account. Repository admins can also rename a branch covered by an organization or enterprise ruleset, but only if the new name stays within the scope of every ruleset that applied to the old one. Otherwise the rename is blocked and an org or enterprise admin must do it, and org and enterprise admins can turn the capability off. This matters for branch-protection governance because bypass lists and rename rights affect who can circumvent required controls.

A collection of drop-in instruction/config files (AGENTS.md, CLAUDE.md, .cursor/rules, .aiignore, etc.) that give AI coding agents a shared security and privacy playbook: never read .env or secrets files, no hardcoded credentials, OWASP hygiene, PII protection, GDPR support, restricted filesystem/network access, no destructive commands without confirmation, mandatory tests, and dependency/CI change controls including typosquatting checks before adding packages. Each tool-specific file (Cursor, Copilot, Windsurf, Cline, Aider, Amazon Q, Junie, Devin, Cody) delegates to one canonical AGENTS.md so teams maintain a single source of truth across all agents in use.

Socket researchers found that Bitwarden CLI 2026.4.0 was compromised via a hijacked GitHub Action in Bitwarden's CI/CD pipeline, part of the ongoing Checkmarx-themed supply chain campaign. The malicious bw1.js payload shares C2 infrastructure and code (gzip+base64 packed Python memory-scraper, Bun-based runtime, GitHub Actions workflow injector) with the earlier Checkmarx mcpAddon.js attack, but adds new indicators like a lock file, shell-profile persistence, and overt "Shai-Hulud: The Third Coming" / Butlerian Jihad ideological branding, plus a kill switch for Russian-locale systems. It harvests GitHub, AWS, Azure, GCP, npm, SSH, and Claude/MCP credentials and exfiltrates via GitHub commits and npm republishing.

Wiz Research breaks down Jenkins' attack surface using cloud environment telemetry: 59% of Jenkins-using environments have critical core vulnerabilities, 87% run end-of-life instances, and plugins like workflow-cps-global-lib (deprecated, 31% adoption) and extended-choice-parameter (unpatched CVEs, 14% adoption) remain widely deployed despite Jenkins' otherwise mature plugin-governance model. The post maps five recurring attack chains observed in the wild - from exposed script consoles used for cryptojacking, through CI/CD pipeline secret extraction, plugin/core exploitation for controller takeover, agent compromise for lateral movement, to IMDS-based cloud credential theft used by actors like Genesis Panda and IntelBroker to pivot into cloud control planes.

SITF Techniques Library is a browsable, searchable knowledge base from Wiz cataloging software supply chain / SDLC attack techniques, filterable by affected component and pipeline stage, in an ATT&CK-style matrix format. The live page content could not be retrieved (the JS app returned no results), so specific technique entries are unverified, but the framework's purpose is to give defenders a structured taxonomy of supply chain attack vectors across the software development lifecycle.

Socket documents a TeamPCP-linked supply chain attack compromising four SAP-affiliated npm packages (mbt, @cap-js/sqlite, @cap-js/db-service, @cap-js/postgres) via a malicious preinstall script that downloads and runs Bun to execute an 11.7MB obfuscated payload. The payload steals SSH keys, cloud/K8s/npm/GitHub credentials, AI tool configs, and crypto wallets, scrapes secrets from CI runner memory bypassing log masking, exfiltrates via attacker-created GitHub repos, self-propagates by publishing trojanized versions of hardcoded SAP CAP dependencies, and persists via Claude Code and VSCode hooks. Socket attributes the campaign with medium confidence to TeamPCP based on shared __decodeScrambled cipher, Russian-locale kill switch, and GitHub-as-C2 patterns previously seen in Checkmarx, Bitwarden CLI, and Trivy incidents.

Socket researchers traced the GitHub account BufferZoneCorp to a cluster of typosquatted RubyGems (knot-prefixed gems impersonating ActiveSupport, Devise, Rack/Rails, and RSpec tooling) and Go modules (mimicking go-retryablehttp, envconfig, and generic infra libraries) that shipped as dormant sleeper packages before later updates added credential theft, GitHub Actions and go.sum tampering, fake go binary wrappers on PATH, and SSH authorized_keys persistence. The Ruby gems exfiltrate SSH keys and AWS, npm, gh, and gitconfig credentials via extconf.rb install hooks to a webhook.site endpoint, while the Go modules disable GOSUMDB, poison GOPROXY, strip go.sum checksums, and hijack the go binary in CI runners. Go's Security team blocked the identified modules after disclosure, but the Ruby gems and GitHub account remained live at time of writing.

Socket's Threat Research team confirms intercom-client@7.0.4, the official Intercom Node.js SDK (~360k weekly downloads), was compromised via a preinstall hook (setup.mjs) that downloads an unverified Bun binary and executes an 11.7MB obfuscated payload (router_runtime.js) which harvests Kubernetes and Vault credentials and exfiltrates them via the GitHub API. The compromise traces to a hijacked maintainer GitHub account (nhur) that pushed spoofed Dependabot-style workflow changes to trigger the npm publish CI pipeline, and the payload closely matches the 'Mini Shai-Hulud' campaign also seen in a PyPI package (lightning) and prior SAP CAP/Cloud MTA npm packages linked to TeamPCP activity.

A practical threat-modelling framework for CI/CD pipelines built from two years of hardening CI/CD configurations. It walks through pipeline-level questions (who can trigger workflows, who can modify workflow definitions) and per-step questions (inputs, branch protection bypass, exposed secrets/OIDC credentials, arbitrary code execution via workflow steps, third-party dependency trust), and gives concrete GitHub Actions examples such as PR-title injection turning into arbitrary code execution and using workflow-exposed VCS credentials to self-approve a PR.

MongoDB's official announcement of Kingfisher, an open-source secret scanner written in Rust that detects hard-coded credentials, API keys, and other secrets across Git repos, commit history, and file systems. Unlike traditional scanners, it actively validates detected secrets by testing them against live cloud/API endpoints to filter out dead credentials, runs entirely on-premises, and is forked/extended from the Nosey Parker project with Tree-sitter-based parsing and 700+ detection rules. MongoDB benchmarks it against TruffleHog and GitLeaks for runtime performance and uses it internally for pre-commit hooks, CI/CD scanning, and historical repo audits.
