What the vulnerability does
The PayPal Forms plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.3. This is due to missing nonce validation on the form creation and management functions. This makes it possible for unauthenticated attackers to create new PayPal forms and modify PayPal payment settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
PayPal Forms versions 1.0.3 and earlier are vulnerable to cross-site request forgery (CSRF). An attacker can craft a malicious webpage that, when visited by a logged-in site administrator, performs unwanted actions on the PayPal Forms configuration without the admin's knowledge or consent. The vulnerability requires the victim to visit the attacker's page while authenticated.
What an attacker can do
Perform unwanted actions on PayPal Forms settings by tricking an authenticated admin into visiting a malicious webpage.
Potential impact on your site
An attacker could modify PayPal Forms configuration or settings if an admin visits a malicious link while logged in.
Conditions required to exploit
The site admin must be logged in and visit an attacker-controlled webpage; no special privileges required.
