CVE-2026-19368

Local file disclosure via unrestricted path reads

Published Aug 9, 2026 · Updated Aug 9, 2026

Path traversal in GemSuite MCP 1.0.0 allows local users to read files accessible to the server via crafted file_path values. The unified Gemini handlers pass file_path and file_paths through request-builder.ts to fs.readFile without confining resolved paths to a trusted root, then embed the Base64 data in an outbound Gemini request. A caller able to invoke the local MCP tools can disclose secrets readable by the server process, but no write or execution impact is reported.
