GHSA-x7cf-6gp3-q5f8
## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-rjxq-qqhf-8hwh. This link is maintained to preserve external references. ## Original Description OpenClaw before 2026.5.12 contains an information disclosure vulnerability in streamable-http MCP servers that forwards operator-configured custom headers during cross-origin redirects. Attackers controlling or compromising an MCP endpoint can redirect requests to exfiltrate sensitive headers like API keys or tenant-routing credentials to attacker-controlled origins.
