Vulnerability Title
Grav Login Plugin 3.8.11 Privilege Escalation via Profile Update
Vulnerability Description
The Grav Login plugin (grav-plugin-login) versions <= 3.8.11 contain a privilege escalation flaw in the authenticated profile self-update handler (processUserProfile(), the update_user task). Unlike the registration handler, this handler does not strip privilege fields ('groups','access') from user-submitted form data before persisting them. When an administrator has added 'groups' and/or 'access' to plugins.login.user_registration.fields and the default 'regular'/DataUser account backend is in use, a low-privilege authenticated user can POST crafted profile form data (e.g. access[admin][super]=true) to escalate to super-admin, enabling admin panel access, scheduler abuse (RCE), and Twig evaluation. Fixed in 3.8.12.

Grav 权限许可和访问控制问题漏洞
Vulnerability Description
Grav Grav是Grav组织开源的一个基于文件系统的无数据库内容管理系统。 Grav 3.8.11及之前版本存在权限许可和访问控制问题漏洞,该漏洞源于经过身份验证的配置文件自更新处理程序(processUserProfile(),update_user任务)在持久化用户提交的表单数据之前未剥离权限字段('groups','access'),可能导致低权限经过身份验证的用户通过特制的配置文件表单数据(例如access[admin][super]=true)提升权限至超级管理员。
