CVE-2019-11744 (GCVE-0-2019-11744)

Vulnerability from cvelistv5 – Published: 2019-09-27 17:17 – Updated: 2024-08-04 23:03
VLAI?
Summary
Some HTML elements, such as &lt;title&gt; and &lt;textarea&gt;, can contain literal angle brackets without treating them as markup. It is possible to pass a literal closing tag to .innerHTML on these elements, and subsequent content after that will be parsed as if it were outside the tag. This can lead to XSS if a site does not filter user input as strictly for these elements as it does for other elements. This vulnerability affects Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1.
Severity ?
No CVSS data available.
