OpenClaw Authorization Bypass Vulnerabilities

Synology OpenClaw versions 2026.2.22 and 2026.2.23 contain an authorization bypass in the synology-chat channel plugin where misconfigured allowlist policies with empty user IDs fail open, allowing authenticated Synology senders to dispatch unauthorized agents and execute downstream tool actions. The vulnerability requires network access and low-complexity exploitation, with a patch currently available.

OpenClaw versions prior to 2026.2.26 contain an authorization bypass vulnerability in Signal group allowlist enforcement where the system incorrectly accepts sender identities derived from direct message (DM) pairing-store approvals. An authenticated attacker with low privileges can exploit this boundary weakness by obtaining DM pairing approval, allowing them to bypass group allowlist checks and gain unauthorized access to Signal groups. While the CVSS score is moderate (3.7) and attack complexity is high, the vulnerability represents a direct authentication control bypass in a messaging security context, and patches are available from the vendor.
