GHSA-6FGP-M6Q4-J3Q5 MCP Run Python Deno Sandbox Misconfiguration Allows SSRF Attacks via Localhost Access

Impact Server-Side Request Forgery SSRF: A security vulnerability exists in the mcp-run-python tool specifically within the Pydantic-AI integration due to an overly permissive Deno sandbox configuration. The tool configures the Deno runtime—which is intended to isolate the execution of untrusted...

CVE-2026-21636

A flaw in Node.js's permission model allows Unix Domain Socket UDS connections to bypass network restrictions when --permission is enabled. Even without --allow-net, attacker-controlled inputs such as URLs or socketPath options can connect to arbitrary local sockets via net, tls, or undici/fetch...

CVE-2026-21636

CVE-2026-21636 describes a security flaw in Node.js’s Permissions model where Unix Domain Socket (UDS) connections can bypass network restrictions even when --allow-net is not enabled. Attacker-controlled inputs (e.g., URLs or socketPath) could reach arbitrary local sockets via net, tls, or undic...
