Grav API 插件（grav-plugin-api）在 1.0.36 版本之前存在一个会话验证不当的漏洞，该漏洞允许已被禁用的账户继续访问 API。原因是 SessionAuthenticator 未对用户账户状态进行强制检查。被禁用的用户可以重用已经授权浏览器或“记住我”会话，在会话过期前调用 API 端点，从而绕过操作员的撤销操作。

Vulnerability Title
Grav API Plugin before 1.0.36 Disabled Account Session Access Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
The Grav API plugin (grav-plugin-api) before 1.0.36 contains an improper session validation vulnerability that allows disabled accounts to keep API access, because SessionAuthenticator does not enforce account state. Disabled users can reuse an already authorized browser or remember-me session to call API endpoints until expiry, defeating operator revocation.
