Protect Your Webinars: Deserialization Vulnerability Found in WebinarIgnition Plugin

CVSScvssV3_1: 9.9

The WebinarIgnition plugin for WordPress sites has been found to have a high severity deserialization of untrusted data vulnerability. Deserialization issues occur when untrusted data is taken from an external source without validation and deserialized into an object that can then be used to manipulate the application’s logic and behavior.

In this case, an attacker could potentially craft a specially formed serialized string and submit it to the WebinarIgnition plugin to be deserialized. This could allow them to execute arbitrary code on the server with the permissions of the web server process. They would then be able to access admin panels, download files, install malware or delete data.

WordPress site owners using the WebinarIgnition plugin should update to the latest version immediately to patch this vulnerability. Version 3.05.0 and below are affected. It is also recommended that you review your server’s access controls and ensure only trusted IP addresses can access the server. Be cautious of any unsolicited message or links claiming to be about this issue.

Staying on top of plugin and theme updates is one of the best ways to protect your WordPress site from security issues like this. Configure updates to happen automatically if possible. Regular backups will also ensure your content and data remain safe should any compromise occur.
