Mozilla has published the advisories (MFSA2025-20, MFSA2025-21, MFSA2025-22, MFSA2025-23 and MFSA2025-24) to address multiple vulnerabilities in Firefox browser. A remote attacker could entice a user running a vulnerable browser to visit a web page with specially crafted content to exploit the vulnerabilities.
Successful exploitation of the vulnerability could lead to remote code execution, denial of service, elevation of privilege, information disclosure, security restriction bypass or spoofing on an affected system.
Mozilla has released new versions of the product to address the issues and they can be downloaded at the following URLs:
Firefox 137 (Windows)
