What the vulnerability does
The Bitly'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.
Explanation of Vulnerability in Simple Terms
Bitly's WordPress Plugin versions 2.7.3 and earlier lack proper authorization checks, allowing authenticated users with low privileges to modify data they should not have access to. The vulnerability requires a valid WordPress account but no special interaction. Site administrators should update to a version newer than 2.7.3 to prevent unauthorized modifications.
What an attacker can do
Modify data in the plugin without proper authorization.
Potential impact on your site
Low-privilege users can alter plugin settings or data, potentially disrupting Bitly link tracking or sharing functionality.
Conditions required to exploit
Attacker must have a low-privilege WordPress account (e.g., subscriber or contributor role).
