Summary Duplicate Advisory: OpenClaw: Trailing-dot localhost CDP hosts could bypass remote loopback protections ### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-fh32-73r9-rgh5. This link is maintained to preserve external references. ### Original Description OpenClaw before 2026.4.2 fails to normalize trailing-dot localhost hosts in remote CDP discovery responses, allowing bypass of loopback protections.
