Description
IBM ContextForge MCP Gateway 1.0.0 through 1.0.11 could allow an authenticated caller to bypass upstream credential-level authorization policies due to an insufficiently specific cache key in the RFC 8693 token exchange cache, enabling reuse of cached upstream bearer tokens across different credentials belonging to the same user.
