CVE-2022-4762 – Materialis Companion < 1.3.40 - Contributor+ Stored XSS via Shortcode

https://notcve.org/view.php?id=CVE-2022-4762

The Materialis Companion WordPress plugin before 1.3.40 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins. The Materialis Companion plugin for WordPress is vulnerable to Stored Cross-Site Scripting via an unknown shortcode in versions up to, and including, 1.3.39 due to insufficient input sanitization and output escaping. This makes it possible for contributor-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. • https://wpscan.com/vulnerability/4500566a-e5f2-40b8-a185-2bcace221b4e • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
