OpenClaw < 2026.2.26 - Authorization Bypass via DM Pairing-Store Leakage in Signal Group Allowlist

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.
