Unknown Essential Real Estate
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 5.3.5 版本之前，Essential Real Estate WordPress 插件在其某个 AJAX 操作中未对以下两项进行验证：所选的房源套餐是否真正免费，以及请求用户是否有权使用该套餐。这导致已自行注册的客户可在未付款的情况下激活付费套餐，并致使网站按该套餐的全价记录一笔已付款发票。
