getgrav Grav是getgrav个人开发者开源的一套可扩展的内容管理系统。 getgrav Grav 1.0.6之前版本存在授权问题漏洞，该漏洞源于授权绕过：API密钥可以用受限的作用域数组创建，但ApiKeyAuthenticator类从不读取或强制执行这些作用域，它加载并返回拥有用户的完整账户对象，因此使用有限作用域（如只读）创建的密钥可以执行拥有用户被授权的任何写入、删除或管理操作。

Vulnerability Title
Grav < 1.0.6 API Key Scope Bypass via ApiKeyAuthenticator
Source: CVE Program / CVE List V5
Vulnerability Description
The Grav API plugin (getgrav/grav-plugin-api) before 1.0.6 contains an authorization bypass: API keys can be created with a restricted scopes array, but the ApiKeyAuthenticator class never reads or enforces these scopes. It loads and returns the owning user's full account object, so a key created with limited scopes (e.g. read-only) can perform any write, delete, or administrative operation the owning user is authorized for. Fixed in 1.0.6.
