Medium

VectorAV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N
Name of the Vulnerable Software and Affected Versions Firefox versions prior to 101
Description The issue is related to incorrect handling of HTML comment tags by the browser's HTML parser, potentially allowing a remote attacker to conduct cross-site scripting attacks. This could be exploited when user-controlled data is placed within HTML comments on a webpage, enabling the attacker to escape the comments.
Recommendations For Firefox versions prior to 101, update to version 101 or later to resolve the issue. As a temporary workaround, consider restricting the use of user-controlled data within HTML comments to minimize the risk of exploitation.
