  • Description: The Smash Balloon Social Post Feed plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.2.1.

It allows unauthenticated attackers to check connection data via a forged request, provided they can deceive a site administrator into performing an action such as clicking on a link.


The Smash Balloon Social Post Feed plugin for WordPress has a vulnerability in versions up to and including 4.2.1 that allows unauthenticated attackers to exploit missing nonce validation to check connection data via forged requests. This vulnerability has been patched in version 4.2.2.

Detailed Overview:

The identified vulnerability in the Smash Balloon Social Post Feed plugin was discovered by researcher Majed Refaea and is related to a Cross-Site Request Forgery (CSRF) issue in the function handling source connection data. By exploiting this vulnerability, attackers could potentially gain unauthorized access to view connection data of social media accounts linked via the plugin. The lack of proper nonce validation means that the plugin does not adequately verify the authenticity of requests, thereby allowing forged requests to be processed. The patched version 4.2.2 addresses this critical security flaw, closing the loophole used by attackers.

What is Cross-Site Request Forgery (CSRF)?

Cross-Site Request Forgery (CSRF) is a web security vulnerability that allows an attacker to induce users to perform actions that they do not intend to perform. It enables an attacker to partially bypass the same-origin policy, which is designed to prevent different websites from interfering with each other. In the context of WordPress plugins, this can mean unauthorized actions being triggered on the website by tricking an authenticated user into clicking a link or loading a page.
