What is CVE-2026-53843?

OpenClaw versions prior to 2026.5.26 are subject to an authorization bypass vulnerability whereby an existing pairing-scoped device session can re-establish node token authority post-revocation. This flaw permits attackers with a paired device to regain unauthorized WebSocket node-level access without the necessity for renewed authorization. Consequently, the effectiveness of revocation controls is compromised, effectively extending unauthorized access beyond intended limits.

Affected Version(s)

OpenClaw 0 < 2026.5.26

OpenClaw 2026.5.26
