A Stored XSS vulnerability in the torrent remaster custom title feature in GazellePW (GazellePosterWall) commit 86c4bedf727691b5a97af42a4864869d18446449 allows remote authenticated users to inject arbitrary JavaScript via the remaster_custom_title parameter, which is stored during torrent upload or edit and later rendered in torrent title output.
AnalysisAI
Stored cross-site scripting in GazellePW's torrent remaster custom title feature allows authenticated tracker members to inject persistent JavaScript that executes in every subsequent visitor's browser. The unsanitized remaster_custom_title parameter is written to the database through both upload and edit code paths (Upload.php, takeedit.php, torrents.class.php) and rendered without encoding, with CVSS Scope Changed confirming cross-user impact. …

Vulnerability AssessmentAI
| Exploitation | Attacker must hold a valid authenticated account on the target GazellePW instance with permission to upload or edit torrents (CVSS PR:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.4 Medium rating reflects a genuine but bounded base risk: network-reachable, low-complexity exploitation requires only a low-privilege account (PR:L) and passive victim interaction (UI:R). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patched version has been identified at time of analysis; the references link only to the vulnerable code, not to a fix commit or release. … Detailed patch versions, workarounds, and compensating controls in full report. |
