Description

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.
