Ubuntu.comUB:CVE-2024-7524CVE-2024-7524
Firefox adds web-compatibility shims in place of some tracking scripts
blocked by Enhanced Tracking Protection. On a site protected by Content
Security Policy in “strict-dynamic” mode, an attacker able to inject an
HTML element could have used a DOM Clobbering attack on some of the shims
and achieved XSS, bypassing the CSP strict-dynamic protection. This
vulnerability affects Firefox < 129, Firefox ESR < 115.14, and Firefox ESR
< 128.1.
