CVE-2023-44766

Date: October 6, 2023

A Cross Site Scripting (XSS) vulnerability in Concrete CMS v.9.2.1 allows an attacker to execute arbitrary code via a crafted script to the SEO - Extra from Page Settings. NOTE: the vendor disputes this because this SEO-related header change can only be made by an admin, and allowing an admin to place JavaScript there is an intentional customization feature.

Language: PHP
