Affected
TYPO3 Extension "Club Directory"
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.
该扩展在前端的编辑、更新和激活操作中，直接从用户提供的请求参数解析目标俱乐部记录，但在所有这些操作中均未执行任何所有权验证。已知俱乐部记录唯一标识符（UID）的未认证访客可以直接向更新或激活操作发送请求，从而覆盖该记录，或将其发布为待审核状态，即使该访客并不拥有该记录。

Vulnerability Title
Broken Access Control in extension "Club Directory" (clubdirectory)
Source: CVE Program / CVE List V5
Vulnerability Description
The extension resolves the targeted club record from a user-supplied request argument in its frontend edit, update, and activate actions, but performs no ownership check in any of them. An unauthenticated visitor who knows the UID of a club record can send a direct request to the update or activate action and overwrite that record, or publish one still awaiting approval, without owning it.
