S2W post on CVE-2026-97229, a CVSS 10.0 remote code execution flaw in the GitLab CE/EE CI/CD regex compiler, disclosed October 13, 2026. Insufficient regex validation plus an integer overflow during encoding conversion lets an attacker who can add CI/CD config use a malicious regex and a UTF-8 repository path to run commands as the git user. Affects self-managed 19.2 before 19.2.8, 19.3 before 19.3.5 and 19.4 before 19.4.2. Rapid7 published analysis and a public PoC exists, with no in-the-wild exploitation confirmed as of October 15. No workaround exists, so patch or restrict access to a management network or VPN.

Orca Security analysis of CVE-2026-97229, a CVSS 10.0 flaw in GitLab CE/EE. An integer overflow (CWE-190) in the CI/CD regular expression compiler gives memory corruption and code execution as the git user. It is triggered by a crafted regex in .gitlab-ci.yml combined with a UTF-8 repository path, with no authentication needed on instances that allow public project creation or self-registration. Lists affected branches (19.2 before 19.2.8, 19.3 before 19.3.5, 19.4 before 19.4.2), the absence of a workaround, interim mitigations, and a Rapid7 PoC against GitLab CE 19.4.1 with ASLR on. Notes a prior max-severity GitLab bug (CVE-2026-85706) was probed in the wild within hours and later added to CISA KEV.

Rapid7 analysis of CVE-2026-97229, a CVSS 10.0 integer overflow (CWE-190) in the Onigmo regex compiler used by GitLab CE/EE's CI/CD regex handling. A crafted regex in a .gitlab-ci.yml passes validation as US-ASCII, then is recompiled for a UTF-8 repository path, producing invalid instructions that give code execution as the git user. Rapid7 reproduced it on GitLab CE 19.4.1 with ASLR (patched in 19.4.2); despite the vendor's "unauthenticated" rating, the attacker needs to commit a malicious config to a public project, which self-registration allows. No in-the-wild exploitation is confirmed, and Rapid7 recommends urgent upgrades.

CVE-2026-57860 describes an arbitrary code execution flaw in ForgeCode (tailcallhq/forgecode), an AI pair-programming CLI that automatically loads and executes MCP servers defined in a repository's .mcp.json on startup without user confirmation. A malicious repo can define mcpServers entries with arbitrary command/args (e.g. bash -c) that spawn under the invoking user's privileges the moment forge is run inside the cloned repo, giving attackers a reliable initial-access and persistence primitive against developers evaluating untrusted code. CVSS 4.0 8.4 HIGH, CWE-829 (inclusion of functionality from untrusted control sphere); a fix commit and VulnCheck advisory are linked.

GHSA advisory for jovancoding/network-ai disclosing that its MCP HTTP transport (bin/mcp-server.ts, lib/mcp-transport-sse.ts) accepts JSON-RPC tools/call requests with zero authentication, session, or origin checks, and binds to 0.0.0.0 by default. The PoC shows an unauthenticated attacker can enumerate 22 registered tools and invoke privileged ones - config_get/config_set to read and mutate live orchestrator configuration, agent_list/agent_spawn/agent_stop, token_create/token_revoke, budget_set_ceiling, and blackboard_write/delete - with curl requests against a local Docker deployment. Remediation recommended enforcing bearer-token auth in _handlePost() before dispatch, defaulting to 127.0.0.1 binding, and gating state-mutating tools behind authorization checks.

GitHub advisory GHSA-jh7p-qr78-84p7 for Claude Code: a malicious repository could ship a project settings file setting ANTHROPIC_BASE_URL to an attacker-controlled endpoint. Claude Code made API requests during project load before the trust prompt was shown, leaking data including the user's Anthropic API key. Fixed in auto-updated versions; manual updaters should upgrade. It is CVSS v4 scored, with network attack vector and passive user interaction, and mapped to a credential-transmission weakness (insecure transmission/storage of credentials).

Solidity 0.8.37 release notes disclosing three EF bug-bounty-reported compiler bugs with security implications: deleting an element of a memory bytes array (or converted string) zeroed the full 32-byte word instead of one byte, corrupting adjacent data in the evmasm pipeline (all versions ≤0.8.36); a stack-to-memory spill-slot collision in mutually recursive functions under --via-ir silently overwrote live variables (0.7.2–0.8.36); and require() with a custom error using named arguments encoded parameters in call-site rather than declaration order, producing structurally valid but semantically wrong revert data. The release also adds two non-security miscompilation fixes, an experimental planning-based stack shuffler for the SSA CFG backend, support for the Amsterdam EVM's SLOTNUM opcode (EIP-7843), and removes/deprecates several experimental features.

GitHub Security Lab discloses GHSL-2026-203 / CVE-2026-84973, a same-second time-of-check-to-time-of-use race condition in the jupyterlab/maintainer-tools update-snapshots-checkout GitHub Action. 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.

Grafana patched CVE-2026-19516 (CVSS 9.1), a critical SSRF in the Grafana MCP server's grafana_api_request tool where a caller-supplied X-Grafana-URL header could control the method, path and body of outbound requests, letting an attacker reach internal-only services from the server's network position. Pillar Security researchers chained this with a second flaw — the MCP server accepting unauthenticated "session-shaped IDs" it never issued — and demonstrated using it to hit the AWS IMDSv2 endpoint and retrieve cloud credentials via a two-step PUT/TTL token request. Grafana MCP v1.1.0 adds optional bearer-token auth to close the session-forgery gap; Pillar frames MCP servers broadly as "identity brokers" that need explicit outbound destination policies and mandatory auth for remote deployments.

Grafana advisory for CVE-2026-19516, a critical (CVSS 9.1) SSRF in mcp-grafana. A caller able to invoke the grafana_api_request tool can set the X-Grafana-URL header to redirect outbound requests, choosing method, path and body, to internal, loopback and link-local services including cloud metadata endpoints, and read the responses. The earlier fix for CVE-2026-15583 only stopped the service-account token leaking to other destinations and did not restrict the destinations; the fix is in version 1.1.0 and later.

CVE-2026-52830 describes a path traversal flaw in fast-mcp-telegram, a PyPI package exposing Telegram as an MCP server, where HTTP Bearer tokens are joined directly into a session-file path without normalization. The verifier blocks the literal reserved token "telegram" but not path separators, so a token like "../fast-mcp-telegram/telegram" lets a remote HTTP client authenticate as the default legacy session, bypassing the control meant to keep multi-user HTTP sessions from colliding with the default stdio/legacy account. Account-prefixed MCP tool naming does not prevent the bypass since prefixed tools for the compromised default account remain accessible.

GHSA-73cv-556c-w3g6 (CVE-2026-49257, CWE-306) documents that mcp-pinot v3.0.1 and earlier defaults to an HTTP MCP server bound to 0.0.0.0:8080 with oauth_enabled=False, exposing all 14 tools — including read_query, create_schema and create_table_config — to any unauthenticated network caller. The server proxies calls using its own server-side Pinot credentials, creating a confused-deputy condition that grants full read/write access to the backing Apache Pinot cluster (CVSS 10.0). Fixed in v3.1.0 (PR #95) by defaulting the bind host to 127.0.0.1, refusing non-loopback exposure without OAuth, and gating Helm exposure behind OAuth.

GitHub changelog entry announcing two repository ruleset changes. 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.

Socket disclosed that a critical sandbox escape in vm2 (GHSA-ffh4-j6h5-pg66, CVE-2026-26956), which lets attacker-controlled JavaScript passed to VM.run() escape isolation and execute arbitrary OS commands via WebAssembly.JSTag, affects far more than the officially listed vm2 3.10.4/Node 25 scope. Socket's testing showed 66 vm2 releases from 0.2.2 through 3.10.4 are exploitable on Node.js 24.15.0, and any Node runtime exposing WebAssembly.JSTag is vulnerable, meaning downstream SCA/scanner tools using the narrower advisory data would miss real exposure. Socket is releasing free Certified Patches (via `socket patch add`) for the issue alongside upgrade guidance to vm2 3.10.5+.

CVE-2026-25536 is a cross-client data leak in the official MCP TypeScript SDK (v1.10.0-1.25.3, CVSS 7.1): when a single McpServer instance reuses a StreamableHTTPServerTransport across multiple concurrent client connections, a race condition in the response multiplexing logic can route one client's tool results, resource content, or errors to a different client. This breaks tenant isolation in multi-user MCP server deployments, a common production pattern, potentially exposing sensitive API responses, file contents, or database query results across security boundaries. Fixed in SDK v1.26.0; recommended mitigations include upgrading, using per-client McpServer instances, and adding client-side response correlation checks.

CVE-2026-21852 describes a flaw in Claude Code versions prior to 2.0.65 where a malicious repository's settings file can override ANTHROPIC_BASE_URL and have it applied during project load before the user sees or accepts the trust-confirmation prompt, causing the user's Anthropic API key to be sent to an attacker-controlled endpoint. The root cause is an initialization-order bug (CWE-522, insufficiently protected credentials) where untrusted repo config is parsed and acted on ahead of trust verification; Anthropic fixed it in 2.0.65 by moving trust checks before config processing. Mitigations include updating, rotating exposed keys, and avoiding opening unfamiliar repos until patched.
