The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.29.9. 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 and above permissions, to reset the password of any user on the site, including administrators, leading to full account takeover and complete site compromise. Exploitation requires the attacker to hold a valid encrypted Current-User token obtained by accessing any Edit User form they are legitimately authorized to submit, which they then use as a known-plaintext base for the CBC bit-flipping forgery.
