CVE-2026-32302Network attack vector

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.
