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

Grav是Grav组织开源的一款基于文件的扁平化内容管理系统。 Grav 1.0.13之前版本存在权限许可和访问控制问题漏洞，该漏洞源于createApiKey函数未验证新创建的API密钥的权限范围是否为调用者权限范围的子集，可能导致攻击者绕过权限范围限制，通过提交空的scopes数组创建无限制的全访问超级密钥，进而实现配置写入甚至远程代码执行。

Vulnerability Title
Grav before 1.0.13 Scope Bypass via createApiKey
Source: CVE Program / CVE List V5
Vulnerability Description
The getgrav/grav-plugin-api plugin before 1.0.13 fails to validate that the scopes of a newly created API key are a subset of the caller's scopes in createApiKey. The self-target path of requireApiKeyPermission() requires only the baseline api.access scope, and the new key's scopes are read directly from the request body with no subset check. An attacker holding a minimal-scope API key on a super account can submit an empty scopes array to mint an unscoped, full-access super key, bypassing scope restrictions (and enabling further chains such as configuration write to RCE).
