What is CVE-2019-19903?

A Cross-Site Scripting vulnerability exists in Backdrop CMS versions 1.14.x prior to 1.14.2, arising from insufficient output filtering in file type descriptions created by administrators. This flaw allows an attacker with the 'Administer file types' permission to inject malicious scripts, which could then be executed when an administrator views the list of file types. Proper input validation and output encoding measures are essential to mitigate this risk.
