CVE-2019-19903 (GCVE-0-2019-19903)

Vulnerability from cvelistv5 – Published: 2019-12-19 05:03 – Updated: 2024-08-05 02:32

Summary

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.

Severity

No CVSS data available.
