WordPress 头部插件曝 9/10 分高危漏洞，官方连发三补丁全失效 WordPress 缓存插件 W3 Total Cache 遭遇严重安全漏洞（CVE-2025-9501），该插件安装量超过100万。漏洞源于插件处理动态内容时使用 PHP 的 eval() 函数，允许攻击者通过在评论中注入代码执行恶意指令。研究人员指出，W3 Total Cache 针对该漏洞发布的2.8.13、2.8.14和2.8.15三个补丁均未能有效修复，存在逻辑缺陷可被绕过。漏洞利用需要攻击者获取 W3TC_DYNAMIC_SECURITY 安全令牌，且网站需允许未登录用户发布评论并开启页面缓存功能。安全专家建议管理员立即审计安全令牌的唯一性，限制未验证用户的评论权限，并审查近期评论日志。IT之家 🏷#W3#Total#Cache#CVE#WordPress 📢频道👥群组📝投稿
