OpenClaw has Signal group allowlist authorization bypass via DM pairing-store leakage
Summary
In OpenClaw 2026.2.25, Signal group authorization under groupPolicy=allowlist could accept sender identities sourced from DM pairing-store approvals. This allowed DM pairing approvals to leak into group allowlist evaluation.
Impact
This is an authorization-boundary weakness between DM pairing and group allowlist controls. A sender approved for DM pairing could pass group checks without explicit group allowlisting.
Affected Packages / Versions
- Package:
openclaw(npm) - Latest published version affected:
2026.2.25 - Vulnerable range:
<= 2026.2.25 - Patched version (planned next release):
>= 2026.2.26
Fix
OpenClaw now keeps DM pairing-store entries DM-only and enforces explicit group allowlist boundaries in shared DM/group policy resolution used by Signal and other channels.
