Date: 2025-11
Affected: npm/@dependencytrack/frontend
Attack vector: xss
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2025-64758
CWE: CWE-79
CVSS: 4.8 (CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N)

### Description Since version 4.12.0, Dependency-Track users with the `SYSTEM_CONFIGURATION` permission can configure a "welcome message", which is HTML that is to be rendered on the login page for branding purposes. When rendering the welcome message, Dependency-Track versions before 4.13.6 did not properly sanitize the HTML, allowing arbitrary JavaScript to be executed. ### Impact Users with the `SYSTEM_CONFIGURATION` permission (i.e., administrators), can exploit this weakness to execute arbitrary JavaScript for users browsing to the login page. ### Patches The issue has been fixed in version 4.13.6. ### References * The issue was introduced via: https://github.com/DependencyTrack/frontend/pull/986 * The issue was fixed via: https://github.com/DependencyTrack/frontend/pull/1378 ### Credit Thanks to *Jonas Benjamin Friedli* for identifying and responsibly disclosing the issue.
