What it is

OpenClaw LINE versions before 2026.8.1 contain an access control vulnerability where group allowlist mode silently inherits DM allowFrom values when groupAllowFrom is not explicitly configured. Attackers with group participation can trigger the agent despite configured group allowlist restrictions when DM access is broader than intended group access.
