## Technical details

The plugin fails to properly authorize user edit requests in its front-end Forms module's update-user action, checking authorization only for administrator accounts. An attacker can exploit misconfigured forms where the target user is derived from visitor input rather than hardcoded to the current user, bypassing all authentication checks to modify credentials of non-admin accounts. This is an improper access control vulnerability (CWE-863) requiring the site to publish a specifically configured form to be exploitable.
