- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=total

- Fixed in: 24.0

## Affected

- WWBN AVideo: fixed in 24.0
- wwbn/avideo (Packagist): all versions

## Description

WWBN AVideo is an open source video platform. Prior to version 24.0, an authenticated Remote Code Execution (RCE) vulnerability was identified in AVideo related to the plugin upload/import functionality. The issue allowed an authenticated administrator to upload a specially crafted ZIP archive containing executable server-side files. Due to insufficient validation of extracted file contents, the archive was extracted directly into a web-accessible plugin directory, allowing arbitrary PHP code execution. This issue has been patched in version 24.0.

## What to do
