Operator access via proxy-exempted WebSocket origin checks
Published Mar 12, 2026 · Updated Mar 12, 2026
Origin validation bypass in OpenClaw before 2026.3.11 allows remote attackers to obtain operator access through a crafted web page. The WebSocket handshake exempts requests carrying an Origin header and proxy headers from the generic origin check, allowing trusted-proxy authentication to retain requested operator scopes. Exploitation requires a victim browser to load an attacker-controlled page that can reach a trusted reverse proxy; verified access exposes configuration and permits operator-class mutations.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
