What is CVE-2026-100566?

OpenClaw LINE versions prior to 2026.8.1 are susceptible to an access control vulnerability, where group allowlist settings fail to properly restrict access. If the 'groupAllowFrom' is not explicitly set, it may inadvertently adopt DM allowFrom values. This oversight permits attackers who are part of the group to exploit broader DM access rights, enabling them to bypass established group allowlist restrictions. It highlights critical concerns for administrators regarding user access configurations and the importance of regular updates.
