Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 5.3.3 版本之前的 Simple Shopping Cart WordPress 插件中，未将用户提交的商品价格与仅站点所有者可设置的值进行比对验证。这导致拥有“贡献者”（Contributor）及以上权限的用户能够为现有商品注册由攻击者指定的价格，而任何访客均可利用该价格将这些商品加入购物车。
