Low severity, CVSS 3.8. EPSS: 0.5% chance of exploitation in the next 30 days.

XenForo before 2.3.13 contains a missing authorization vulnerability in the force-agreement controller that allows any ACP administrator to access and submit force-agreement forms regardless of their assigned permissions.
