CVE-2019-19903 Information

Description

An issue was discovered in Backdrop CMS 1.14.x before 1.14.2. It doesn’t sufficiently filter output when displaying file type descriptions created by administrators. An attacker could potentially craft a specialized description then have an administrator execute scripting when viewing the list of file types aka XSS. This vulnerability is mitigated by the fact that an attacker must have a role with the \Administer file types\ permission.
