CVE-2026-7802: Frontend Admin by DynamiApps <= 3.29.2 - Missing Authorization to Authenticated (Subscriber+) Account Takeover via 'user_id' URL Query Parameter

The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.29.2. This is 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 userpass, useremail, firstname, lastname, and other profile fields by supplying an arbitrary ?userid= 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, loaddata() sets the user ID to 'none' for users whose roles fall outside the allowed list, preventing administrators from being targeted through that form.
