Description

OpenClaw before 2026.5.7 contains a privilege escalation vulnerability where the allowFrom feature improperly validates Discord account identity using mutable display names instead of immutable user IDs. Attackers with Discord accounts can change their display name to match a policy entry and gain unauthorized agent access intended for another Discord identity.
