Quick assessment

Affected
Unknown WPBot
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.

WPBot WordPress 插件在 8.5.7 版本之前，未对多个用于向已配置的 AI 提供商转发提示词（prompts）的 AJAX 操作执行任何身份验证或 nonce（令牌）检查。这使得未认证的攻击者能够利用该站点自身配置的 API 密钥，发起对这些第三方 API 的调用，并由此产生相应的调用成本。
