This is due to insufficient file type validation in check_mimetype(), which writes attacker-supplied remote file content to the public uploads directory before any MIME or extension check, combined with a missing capability check on new player creation. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload files that may be executable, which makes remote code execution possible. This requires successfully exploiting a race condition.\nhttps://www.cve.org/CVERecord?id=CVE-2026-83526https://www.wordfence.com/threat-intel/vulnerabilities/id/5c75cb7b-1ebe-411c-8664-848d741e40d4?source=cvehttps://plugins.trac.wordpress.org/browser/fv-player/trunk/models/checker.php#L105https://plugins.trac.wordpress.org/browser/fv-player/trunk/models/checker.php#L148https://plugins.trac.wordpress.org/browser/fv-player/trunk/models/checker.php#L181https://plugins.trac.wordpress.org/browser/fv-player/trunk/models/db.php#L46https://plugins.trac.wordpress.org/browser/fv-player/trunk/models/db.php#L1102https://plugins.trac.wordpress.org/browser/fv-player/trunk/models/db.php#L1173https://plugins.trac.wordpress.org/browser/fv-player/trunk/models/db-video.php#L855https://plugins.trac.wordpress.org/browser/fv-player/trunk/controller/editor.php#L36https://plugins.trac.wordpress.org/browser/fv-player/trunk/controller/frontend.php#L1211https://github.com/foliovision/fv-wordpress-flowplayer/releases/tag/8.1.8#wordpress #foliovision #FVPlayer8#CVE_2026_83526#bot", "creation_timestamp": "2026-10-10T05:53:53.549779Z"} 2026-10-10T05:53:53.549779+00:00
