What the vulnerability does
The Zapier for WordPress plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.5.1 via the updated_user() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to make web requests to arbitrary locations originating from the web application which can be used to query and modify information from internal services.
Explanation of Vulnerability in Simple Terms
The Zapier for WordPress plugin versions 1.5.1 and earlier contain a server-side request forgery vulnerability. An authenticated user with low privileges can make the site send HTTP requests to internal or external systems on the attacker's behalf. The vulnerability affects the scope beyond the plugin itself, potentially exposing internal network resources or allowing interaction with third-party services.
What an attacker can do
Make the site send HTTP requests to internal networks or external systems without authorization.
