What the vulnerability does
The WP Rocket plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.21.0.1. This is due to insufficient input sanitization and output escaping of user-supplied data via the rocket_beacon AJAX endpoint. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
WP Rocket versions up to 3.21.0.1 contain a cross-site scripting vulnerability that allows unauthenticated attackers to inject malicious scripts into the site. The vulnerability affects the scope beyond the vulnerable component, potentially impacting other parts of the application. Site administrators should update to a version newer than 3.21.0.1 to remediate this issue.
What an attacker can do
Inject malicious JavaScript that executes in visitors' browsers and affects other site functionality.
Potential impact on your site
Visitors' browsers could execute attacker-controlled scripts, potentially stealing data or redirecting users.
