Grav API Plugin是Grav组织的一款提供API接口功能的插件。 Grav API Plugin 1.0.8之前版本存在授权问题漏洞，该漏洞源于user/plugins/api/api.php文件中对apiKeyGenerate和apiKeyRevoke管理任务的权限验证不足，仅以admin.login权限授权调用，导致基础面板用户可选择其他账户创建持久凭据并继承目标API权限，包括api.super或管理写访问权限，造成权限提升。

Vulnerability Title
Grav API Plugin: Missing authorization on API-key generate/revoke lets any admin.login user forge keys for any account
Source: CVE Program / CVE List V5
Vulnerability Description
Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content. Prior to 1.0.8, the Grav API plugin intercepts the apiKeyGenerate and apiKeyRevoke admin tasks in user/plugins/api/api.php and authorizes the caller with only admin.login. A basic panel user can select another account from the route, create a persistent ApiKeyManager credential bound to that target, and inherit the target's API permissions, including api.super or administrative write access when present. This issue is fixed in version 1.0.8.
