CVE-2026-52869: CWE-639: Authorization Bypass Through User-Controlled Key in modelcontextprotocol python-sdkCVE-2026-52869 0 A vulnerability in the Model Context Protocol (MCP) Python SDK prior to version 1.27.2 allows authorization bypass. The issue occurs because certain transports route requests to sessions based solely on session identifiers without verifying the authenticated user who created the session. This enables an attacker with a known session ID and bearer token to inject JSON-RPC messages into another user's session. The vulnerability is fixed in version 1.27.2.
