CVE-2024-7524

Summary

CVE-2024-7524 is a vulnerability in Firefox affecting versions below 129, Firefox ESR below 115.14, and Firefox ESR below 128.1. Firefox implements web-compatibility shims instead of blocked tracking scripts due to Enhanced Tracking Protection. When a site utilizes Content Security Policy in "strict-dynamic" mode, attackers can inject an HTML element and perform a DOM Clobbering attack on certain shims, leading to Cross-Site Scripting (XSS) and bypassing CSP strict-dynamic protection.
