Executive Summary

The WordPress Pods Plugin, versions up to and including 3.3.8, contains a Cross Site Scripting (XSS) vulnerability. This means attackers can inject malicious scripts into the website, which are then executed when visitors access the site.

Exploitation requires a privileged user to perform an action such as clicking a malicious link or submitting a form, which then allows the attacker to execute scripts like redirects or advertisements on the site.

This vulnerability has a medium priority with a CVSS score of 7.1 and is patched in version 3.3.9.

Detection Guidance

This vulnerability affects WordPress sites running the Pods Plugin version 3.3.8 or earlier. Detection involves verifying the plugin version installed on your WordPress site.

You can check the Pods plugin version by accessing your WordPress admin dashboard under Plugins, or by running commands on the server hosting the site.

• Use WP-CLI to check the plugin version: wp plugin list | grep pods
• Check the plugin version in the plugin's main PHP file, usually located at wp-content/plugins/pods/pods.php, by running: grep 'Version' wp-content/plugins/pods/pods.php

Additionally, monitoring for suspicious script injections or unexpected redirects in website traffic logs or web application firewall alerts may help detect exploitation attempts.
