CVE-2026-73317
XenForo before 2.3.13 contains a missing authorization vulnerability in the ACP cache-rebuild dispatcher that allows limited administrators with only the rebuildCache permission to perform unauthorized approval queue actions by supplying an arbitrary job class and actor user ID in the POST body. Attackers can invoke the approval queue job under any user identity to approve queued user registrations without holding the required approval-queue or moderator permissions, causing the moderation log to attribute actions to an impersonated account.
