CVE-2023-5723

Name of the Vulnerable Software and Affected Versions Firefox versions prior to 119

Description The issue is related to insufficient input validation when handling cookies, which could allow a remote attacker to execute arbitrary code. An attacker with temporary script access to a site could set a cookie containing invalid characters using document.cookie, potentially leading to unknown errors.

Recommendations For versions prior to 119, update to Firefox version 119 or later to resolve the issue. As a temporary workaround, consider restricting the use of the document.cookie until a patch is available.
