CVE-2026-38466 · Severity: medium · CVSS 5.4 · Published 2026-08-25

GazellePW is a web-based torrent tracker application. A stored cross-site scripting (XSS) vulnerability allows authenticated users to inject malicious JavaScript code into torrent titles during upload or editing. When other users view the affected torrents, the injected code executes in their browsers, potentially enabling session hijacking, credential theft, or malware distribution.

## Technical details

The vulnerability is a stored XSS flaw in the remaster_custom_title parameter within GazellePW's Upload.php component (commit 86c4bedf). User-supplied input from the remaster_custom_title field is not properly sanitized or encoded before being stored in the database and later rendered in torrent title output. An authenticated user can inject arbitrary JavaScript that persists and executes for all other users who view the affected torrent. The attack requires prior authentication to access the upload/edit functionality, and the payload is stored persistently rather than reflected. No patch information is currently available in the advisory.
