AVideo Vulnerable to Remote Code Execution via Persistent PHP Temp File in Encoder downloadURL with Resolution Validation Abort
Description
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.
