Does this matter?

Lower severity and a low EPSS score (0.15%). Track it; it rarely justifies an emergency change on its own.

Description

OpenClaw versions prior to 2026.2.26 contain an authorization bypass vulnerability where Signal group allowlist policy incorrectly accepts sender identities from DM pairing-store approvals. Attackers can exploit this boundary weakness by obtaining DM pairing approval to bypass group allowlist checks and gain unauthorized group access.
