A GitHub PoC chaining two n8n CVEs into unauthenticated RCE: CVE-2026-21858 abuses a Content-Type confusion in the Form Trigger/Respond-to-Webhook nodes to read arbitrary files (e.g. /proc/self/environ, the SQLite database, and the config file), from which the attacker derives the JWT secret from n8n's encryptionKey and forges an admin session cookie. That admin access is then used to create a workflow exploiting CVE-2025-68613, an expression-injection sandbox bypass (`this.process.mainModule.require`) that yields command execution, all demonstrated with a working Python exploit script and Docker lab against n8n 1.65.0. It notes the exploit was developed independently of a prior Cyera/Dor Attias write-up on a related n8n chain and details the specific vulnerable workflow pattern (file-upload form + binary Respond node) required for exploitation.

VulnHunter is a maintained fork of Capital One's open-source agentic security scanner, reworked to run on any agent harness (Claude Code, Codex, Grok/OpenCode) instead of being Claude-Code-specific. The fork's distinguishing work is engineering, not security findings: portable "skill" prompt files with an explicit environment contract, an installer that fails loudly instead of guessing paths, Docker-based sandboxed exploit validation, and a benchmark harness that ran six full scans of one production Go service across five model/harness stacks, finding that result counts swung from 3 to 42 findings depending on how rigorously exploits were validated. It ships three composable skills (/vulnhunt, /vulnhunter-fix, /vulnhunt-fix-verify), a headless batch-runner (harness/), and a deterministic manifest-writing CLI (vh).

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.

Pipelock is an open-source (Apache 2.0 core) AI agent firewall that sits between agents and the network, mediating HTTP, WebSocket, MCP, and A2A traffic to detect secret exfiltration, prompt injection, SSRF, and MCP tool poisoning. It scans request/response bodies with a DLP engine (65 built-in patterns, checksum validation), streaming SSE inspection, and MCP tool-call chain analysis, then emits Ed25519-signed, hash-chained action receipts so decisions can be verified offline outside the agent runtime. It also offers OS-level containment (Landlock/seccomp/sandbox-exec), a kill switch, canary tokens, and integrations for Claude Code, Cursor, VS Code, OpenAI Codex, LangGraph, CrewAI, and other agent frameworks.

A reference implementation from Anthropic showing how to build a Claude-powered vulnerability discovery and remediation pipeline: interactive skills (/threat-model, /vuln-scan, /triage, /patch, /customize) for static scoping, scanning, triage and patch generation, plus an autonomous seven-stage recon-find-verify-dedupe-report-patch harness that builds targets with Docker/ASAN and runs each agent in a gVisor sandbox with restricted egress. It also ships a detection-and-response track (/dnr-hunt, /dnr-respond) for hunting an attacker already present in logs, scoping blast radius, and proposing a response, demoed against a planted attack campaign in synthetic logs.

AG Kit is an open-source Antigravity-first agent engineering toolkit that installs a `.agents/` workspace contract of rules, skills, specialist agents, workflows, persistent memory, and MCP configuration for Google's Antigravity coding-agent runtime. It ships a native PreToolUse safety hook that blocks destructive commands (root-filesystem deletion, drive formatting, raw-disk overwrites) without replacing Antigravity's own permissions or sandboxing, plus a CLI (`ag-kit init`/`update`/`rollback`) with merge-aware, backed-up updates and SemVer-versioned, drift-checked toolkit manifests.

A 258-item, 17-category security checklist targeting vulnerabilities that AI coding assistants (Claude, GPT, Gemini, Grok, Mistral, Copilot) commonly introduce, each item tagged with severity and a static/runtime/config detection method. Includes a companion prompt.md that turns the checklist into an automated scan runnable via Claude Code, Gemini CLI, or OpenAI Codex CLI against a local codebase, covering issues like prompt injection via user-supplied system prompts, missing auth middleware, hardcoded secrets, exposed API keys in frontend env vars, LLM-based auth decisions, unsandboxed agentic shell/filesystem access, and vector DB tenant isolation gaps.
github.comrepoAdded 3 Sep 2026, published 13 May 2026🛡️ Security - IDP Zero-Dollar
A companion GitOps playbook/repo for building a free, self-hosted "AWS-equivalent" Kubernetes platform from three bare-metal Linux boxes using k3s, Cilium, cert-manager, Traefik, Argo CD, Forgejo, Vault, Keycloak, kube-prometheus-stack, Loki, Kyverno, and Velero. It walks through the full security-relevant stack end to end: OS hardening (SSH lockdown, ufw, fail2ban), Cilium NetworkPolicy as CNI, Let's Encrypt DNS01 wildcard certs, Vault as the source of truth for secrets synced via External Secrets Operator (never committing secrets to Git), Keycloak OIDC for centralized identity across Argo/Grafana/Forgejo/Vault, Kyverno pod-security policies in audit-then-enforce mode, and Velero + Vault Raft snapshot backup/DR with quarterly restore drills. It closes with a candid list of what self-hosting gives up versus managed cloud (CVE patch cadence, DDoS exposure, compliance evidence, etcd/HA operational risk).

deepsec is an open-source, agent-powered vulnerability scanner from Vercel Labs designed for on-demand AI review of large existing codebases, using maximum-thinking-level LLMs (routed via Vercel AI Gateway or a bring-your-own OpenAI/Anthropic key) to surface long-lurking, hard-to-find bugs. It fans work across worker machines or Vercel Sandbox microVMs for parallel scanning, supports resumable/interruptible runs with cost and time caps, and exports findings as reports; its docs explicitly discuss the prompt-injection risk of running an agent with shell access over untrusted vendored code.
github.comrepoAdded 3 Sep 2026, published 13 May 2026🛡️ Security - PentHertz/LUKSbox
LUKSbox is an open-source (Apache 2.0), pre-1.0 encrypted vault format and CLI/GUI/TUI toolset written in Rust, designed so files can be stored on untrusted cloud/shared media while remaining opaque to the provider. It layers passphrase, FIDO2 hardware authenticators (hmac-secret), and TPM 2.0 sealed keys as unlock factors that all derive a Master Volume Key via HKDF-SHA256, and adds an optional ML-KEM-768/1024 post-quantum sidecar for hybrid encryption. The project publishes its on-disk format spec, threat model, and side-channel notes, and runs libFuzzer/AFL++ harnesses against every parser that touches attacker-controlled bytes (header, keyslot, metadata, hybrid sidecar, WinFsp paths).
github.comrepoPublished and added 8 May 2026🛡️ Security - SanMuzZzZz/LuaN1aoAgent
LuaN1aoAgent v2 is a TypeScript rewrite of an autonomous, authorized security-research agent built on the Pi SDK, splitting work into Planner, Executor, and Observer (Supervisor/Projector) roles that coordinate via a persisted task graph and an evidence-backed reasoning/operation graph. It runs Executors in per-task Docker sandboxes with a protocol-aware Go network Gateway that enforces IP/domain scope, supports CVE/advisory lookups via NVD and web search, browser rendering, and traffic capture/replay through an authenticated web workbench. The project targets authorized pentesting/CTF-style engagements, with explicit scope enforcement, SOCKS5 egress routing, and human-facing observability (TUI + web UI) for tracing hypotheses to confirmed vulnerabilities and exploits.

PentestAgent (GhostCrew) is an LLM-powered pentesting agent with a TUI that runs single-shot, autonomous-agent, or multi-agent "crew" modes against a target, backed by built-in terminal/browser/notes tools and prebuilt black-box attack playbooks. It supports Docker/Kali images preloaded with nmap, Metasploit, sqlmap and hydra, exposes itself as an MCP server for external clients, and can spawn hierarchical child agents over MCP (with RAG-based tool selection) to delegate recon subtasks in parallel.
github.comrepoPublished and added 8 May 2026🛡️ Security - IronCurtain: Secure AI Agent Runtime
IronCurtain is a research-prototype runtime that constrains autonomous AI agents (Claude Code, Goose, or its own builtin agent) by compiling a human-written "constitution" into deterministic policy rules enforced on every MCP tool call. It treats the LLM as untrusted, mediating all filesystem/git/network/API access through a policy engine (allow/deny/escalate), a V8 isolate sandbox for its builtin agent, and a network-isolated Docker mode with a TLS-terminating MITM proxy for external agent tools. It also ships multi-agent workflow orchestration (e.g., a vulnerability-discovery pipeline with libFuzzer/AFL++ fuzzing gates) with human approval checkpoints.
