Frontend Admin by DynamiApps < 3.29.3 - Subscriber+ Account Takeover via 'user_id' URL Query Parameter

Description

The plugin is vulnerable to authorization bypass due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to overwrite an administrator's user_pass, user_email, first_name, last_name, and other profile fields by supplying an arbitrary ?user_id= value, enabling full administrator account takeover via direct password replacement or email-redirect password reset. Exploitation requires the targeted Edit-User form to have its 'Roles' configuration setting left empty; when a non-empty roles list is configured, load_data() sets the user ID to 'none' for users whose roles fall outside the allowed list, preventing administrators from being targeted through that form.
