Summary Duplicate Advisory: OpenClaw: CDP /json/version WebSocket URL could pivot to untrusted second-hop targets ### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-f7fh-qg34-x2xh. This link is maintained to preserve external references. ### Original Description OpenClaw before 2026.4.5 contains a server-side request forgery vulnerability in the CDP /json/version WebSocket endpoint that allows attackers to pivot to untrusted second-hop targets. The webSocketDebuggerUrl response field is not properly validated, enabling attackers to redirect connections to arbitrary hosts and perform SSRF-style attacks.
