CVE-2026-77363 · obsidian-tc Streamable HTTP transport permits cross-origin loopback vault access
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
obsidian-tc is a governed, agent-ready Model Context Protocol server for Obsidian vaults. Prior to 1.3.1, the Streamable HTTP transport does not validate the Host or Origin header or enable DNS-rebinding protection. When the documented loopback configuration uses auth.mode set to none, a malicious web page can send requests to the local MCP endpoint and receive unrestricted vault access through the http-local caller. Version 1.3.1 fixes the vulnerability by enabling host, origin, and DNS-rebinding validation.
