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, and is only exploitable if the '[fvplayer_editor]' shortcode is present, or the \"Enable profile videos\" setting is enabled."}], "lastModified": "2026-10-28T17:18:44.107", "sourceIdentifier": "security@wordfence.com"}
