A fix is available — apply it.

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.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
