| Vector | AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N |
Name of the Vulnerable Software and Affected Versions
Firefox versions prior to 69
Firefox ESR versions prior to 60.9
Firefox ESR versions prior to 68.1
Thunderbird versions prior to 60.9
Thunderbird versions prior to 68.1
Description
The issue is related to certain HTML elements, such as
title and textarea, which can contain literal angle brackets without being treated as markup. This allows an attacker to pass a literal closing tag to .innerHTML on these elements, causing subsequent content to be parsed as if it were outside the tag. This can lead to cross-site scripting (XSS) attacks if a site does not filter user input strictly for these elements.Recommendations
For Firefox versions prior to 69, update to version 69 or later.
For Firefox ESR versions prior to 60.9, update to version 60.9 or later.
For Firefox ESR versions prior to 68.1, update to version 68.1 or later.
For Thunderbird versions prior to 60.9, update to version 60.9 or later.
For Thunderbird versions prior to 68.1, update to version 68.1 or later.
