TREK before 3.3.0 registered get_trip_summary for scoped OAuth MCP tokens without requiring trips:read (CVE-2026-77321). OpenWA before 0.23.5 let a VIEWER-level key call the GroupGetInviteCode MCP tool (CVE-2026-91161). IBM ContextForge MCP Gateway 1.0.0 through 1.0.8 used str.startswith() for path confinement in its log-download endpoint (CVE-2026-77825). (NVD) The same mistake three times: the MCP tool layer got added next to a REST API and didn't inherit that API's permission checks. A tool registry needs its own authorization test per tool, written against the tool, not against the route it wraps.

CVE-2026-90474, published September 12 at CVSS 7.6, is an authentication bypass in MCPHub's embedded OAuth 2.0 authorization server: client authentication is off by default and PKCE enforcement is optional (NVD). Two days after the Langflow and ContextForge cluster, the same s...
Between September 14 and September 15, NVD published seven entries hitting MCP infrastructure. I read all of them expecting to find something clever. There's nothing clever in any of them. CVE-2026-57124, 9.8, published September 14. PraisonAI's default UI exposes POST /api/mc...
The trick is one line in a file you never read. Manifold Security published eight findings across seven coding agents (Claude Code, Codex, Cursor, Grok Build, Qwen Code, goose, Hermes Agent) that all reduce to the same mechanism. A repository's own .git/config sets core.fsmoni...
The single biggest cross-agent story this week isn't one CVE. It's that MCP became the dominant agent-hijack surface, and this is the defense that actually stops it. The pattern across a dozen findings: Sentry's MCP server weaponized via fake error events for an 85% agent-hija...
Terra Security's adversarial testing found recurring vulnerability patterns across AI coding tools including Claude Code, Loveable, and Base44. CVE-2026-25724 is a path traversal vulnerability in Claude Code (pre-2.1.7) where symbolic links bypass deny rules in settings.json b...
