Quick assessment

Affected

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.

Grav API 插件（getgrav/grav-plugin-api）在 1.0.18 版本之前存在一个漏洞。在 BlueprintController 的 injectSecurityTab() 函数中，该插件未正确应用 API 密钥的作用域限制，用于判断页面的安全性/权限蓝图部分是否可编辑。由于该函数直接执行原始的 isSuperAdmin() 或 hasPermission() 检查，且不依赖于请求参数，因此无法强制实施 scopeAllows() 限制。这意味着，拥有受作用域限制的 API 密钥的用户可能

Vulnerability Title
Grav before 1.0.18 Authentication Bypass via Scoped API Key
Source: CVE Program / CVE List V5
Vulnerability Description
The Grav API plugin (getgrav/grav-plugin-api) before 1.0.18 does not apply the API-key scope cap in the injectSecurityTab() function of BlueprintController when deciding whether a page's security/permissions blueprint section is editable. Because the function performs raw isSuperAdmin()/hasPermission() checks without a request parameter, it cannot enforce scopeAllows(). A caller holding a scoped API key may therefore see (and potentially edit) page permission fields beyond the scope granted to the key. The end-to-end write-time impact was not fully confirmed by the reporter.
