CVE-2023-23604

Name of the Vulnerable Software and Affected Versions Mozilla Firefox versions prior to 109

Description The issue is related to the implementation of the ParseFromSafeString() function in the DOMParser interface of Mozilla Firefox. It involves the incorrect creation of a duplicate SystemPrincipal object when handling html documents. This could allow a remote attacker to bypass security restrictions.

Recommendations For versions prior to 109, update to version 109 or later to resolve the issue. As a temporary workaround, consider restricting the use of the DOMParser::ParseFromSafeString function until a patch is available.
