CVE-2026-105699 is an authorization bypass vulnerability in langflow versions 1.6.8 through 1.9.0. It allows a user with access to any project-scoped MCP endpoint to read another user's private flow-backed files without proper authorization. The flaw arises because the resource URI supplied by the user is not verified to belong to the authenticated user or project. This vulnerability exposes sensitive uploaded documents, structured data, prompts, and other private artifacts but does not allow modification of victim files or flows. The issue is fixed in langflow version 1.9.1.
