Quick assessment

Affected
Unknown BackWPup
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.

在 BackWPup WordPress 插件版本 5.7.7 之前，该插件未验证对其由 cron 触发的备份执行处理程序的请求是否确实源自 WordPress 的内部计划事件分发机制，这使得未经身份验证的攻击者能够强制立即运行任何现有的备份作业，而与该作业配置的触发类型或计划无关。
