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.

Vulnerability Title
Grav API Plugin 授权问题漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
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。
