CyberRota Analysis
AI-GeneratedThe Grav Login plugin versions up to 3.8.11 are vulnerable to a privilege escalation flaw that allows low-privilege authenticated users to manipulate their profile data and gain super-admin access. This vulnerability can lead to unauthorized access to the admin panel, remote code execution, and potential exploitation of the Twig templating engine. Administrators using affected versions should prioritize updating to version 3.8.12 to mitigate these risks.

Original NVD 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.
