Description
This security bulletin contains information about 1 security vulnerability.
1) Security features bypass (CVE-ID: CVE-2024-7524)
The vulnerability allows a remote attacker to bypass CSP policy.
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.
