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InvitationsController未能强制执行API密钥范围限制，strip-super和accept-groups决策仅基于isSuperAdmin()检查而非范围感知权限检查，可能导致低权限API密钥创建包含超级管理员访问标志的邀请记录，进而导致权限提升。

Vulnerability Title
Grav before 1.0.13 API Key Scope Bypass via InvitationsController
Source: CVE Program / CVE List V5
Vulnerability Description
Grav Plugin API (getgrav/grav-plugin-api) before 1.0.13 fails to enforce API-key scope caps in InvitationsController. The strip-super and accept-groups decisions are gated on a bare isSuperAdmin() check rather than a scope-aware permission check, so a least-privilege API key (scoped to api.users.write) minted on a super account can create an invitation record containing super-admin access flags. When the invitation is accepted, those flags are written verbatim to the new account, resulting in privilege escalation to a fully controlled super account.
