  "details": "WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `downloadVideoFromDownloadURL()` function in `objects/aVideoEncoder.json.php` saves remote content to a web-accessible temporary directory using the original URL's filename and extension (including `.php`). By providing an invalid `resolution` parameter, an attacker triggers an early `die()` via `forbiddenPage()` before the temp file can be moved or cleaned up, leaving an executable PHP file persistently accessible under the web root at `videos/cache/tmpFile/`. Commit 6da79b43484099a0b660d1544a63c07b633ed3a2 contains a patch.",
