Summary

The grav-plugin-admin plugin in version 1.10.52 and earlier allows an authenticated attacker with admin.users permission to change the password of any user account, including the super administrator. The vulnerability exists because the saveUser function only checks general user-management permissions but does not verify whether the caller is authorized to edit the target user.

Risk Assessment

The organization is at risk of a super administrator account takeover by an attacker with basic administrative privileges, potentially leading to full compromise of the Grav system and complete control over the website.

Recommendation

Immediately update the grav-plugin-admin plugin to version 1.10.53 or later, which contains the fix for this vulnerability.

Original NVD description (English source)

grav-plugin-admin is an HTML user interface that provides a way to configure Grav and create and modify pages. In 1.10.52 and earlier, an authenticated attacker with admin.users permission can change the password of any user account, including the super administrator, by sending a direct POST request to /admin/user/{username}?task=save with data[password] because saveUser authorizes the caller's user-management permission but does not verify whether the caller may edit the target user. This issue is expected to be fixed in version 1.10.53.
