This medium-severity CVE scores 5.4 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 88% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

WWBN AVideo is an open source video platform. Prior to version 26.0, WWBN/AVideo contains a stored cross-site scripting vulnerability in the CDN plugin's download buttons component. The clean_title field of a video record is interpolated directly into a JavaScript string literal without any escaping, allowing an attacker who can create or modify a video to inject arbitrary JavaScript that executes in the browser of any user who visits the affected download page. Version 26.0 fixes the issue.
