XSS in Wwbn Avideo
CVE-2026-92584
AVideo through 29.0 (current revision e01e41ecc) contains a stored cross-site scripting vulnerability. The unauthenticated view-counter endpoint objects/videoAddViewCount.json.php reaches VideoStatistic::save(), which writes the caller's User-Agent (via getUserAgentInfo(), which returns unrecognized agent strings verbatim) directly into the `app` column of the videos_statistics table without invoking the sanitizing setter setApp(); normalizeApp() only truncates the value to 45 characters. The video owner's and administrator's statistics page (view/videoViewsInfo.php) renders this field in a DataTables 1.12.1 column with an unescaped renderer, and DataTables assigns cell content using innerHTML, so attacker-supplied HTML is parsed and executed in the privileged user's authenticated session when the statistics page is viewed. No patched version was available at the time of the advisory.
