CVE-2026-53843Network attack vector

Node access persistence via surviving pairing session

Published Jun 16, 2026 · Updated Jun 16, 2026

Authorization bypass in OpenClaw before 2026.5.26 allows remote authenticated users to regain revoked node WebSocket access. A surviving same-device session retaining pairing-related scope re-establishes node token authority after revocation without the normal approval flow. Exploitation requires an already paired device with a live pairing-scoped session, and the consequence is continued node-level access.
