Recommendation: Monitor — no exploitation signal at the moment.

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.
