Quick assessment

Affected
XenForo XenForo
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

XenForo 2.3.13 之前的版本存在一个授权缺失漏洞。该漏洞位于后台控制面板（ACP）的缓存重建调度器中，允许仅拥有“重建缓存”权限的受限管理员通过在 POST 请求体中提供任意任务类和操作者用户 ID，执行未授权的审批队列操作。攻击者可以以任意用户身份调用审批队列任务，在并不拥有必要的审批队列或版主权限的情况下，批准排队中的用户注册请求，导致审核日志将这些操作记录在被冒用的账户名下。

Vulnerability Title
XenForo < 2.3.13 Missing Authorization via ACP Cache-Rebuild Dispatcher
Source: CVE Program / CVE List V5
Vulnerability Description
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.
