Overview
wwbn/avideo is an Audio and Video Platform or simply "A Video Platform".
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the aVideoEncoderChunk.json.php endpoint. An attacker can exhaust server disk space by sending large or repeated POST requests, causing persistent temporary files to accumulate without cleanup. This can lead to service disruption and potential exposure of filesystem paths through the response JSON. The attack can be distributed via browsers due to permissive CORS settings, and does not require authentication.
