DescriptionCVE.org
IBM ContextForge MCP Gateway 1.0.0 through 1.1.0 is vulnerable to improper credential handling because the X-Upstream-Authorization request header can override the gateway-managed upstream credential for OAuth (authorization_code and client_credentials), bearer and basic authenticated gateways, which could allow an authenticated user to cause upstream requests to be made with a different credential and bypass per-user permission and audit attribution.
