Bitly's WordPress Plugin <= 2.7.3 - Missing Authorization to Authenticated (Subscriber+) Settings Update

The Bitly&#039;s WordPress Plugin plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on several AJAX actions in all versions up to, and including, 2.7.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update and retrieve plugin settings.
