OpenClaw versions prior to 2026.2.26 contain an authorization bypass vulnerability where DM pairing-store identities are incorrectly eligible for group allowlist authorization checks. Attackers can exploit this cross-context authorization flaw by using a sender approved via DM pairing to satisfy group sender allowlist checks without explicit presence in groupAllowFrom, bypassing group message access controls.
