Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

KeyWord Collector WordPress 插件（版本 1.4 及之前版本）在保存其设置时未进行任何身份验证或非ce nonce（一次性令牌）检查，且在输出设置内容前也未对其进行转义处理。这使得未认证的攻击者能够存储恶意 JavaScript 代码，当管理员访问 KeyWord Collector 插件的设置页面，或访客加载显示该插件输出的页面时，恶意脚本将被执行。
