CVE-2026-33764: Wwbn Avideo

Medium severity, CVSS 4.3. EPSS: 0.3% chance of exploitation in the next 30 days.

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the AI plugin's `save.json.php` endpoint loads AI response objects using an attacker-controlled `$_REQUEST['id']` parameter without validating that the AI response belongs to the specified video. An authenticated user with AI permissions can reference any AI response ID — including those generated for other users' private videos — and apply the stolen AI-generated content (titles, descriptions, keywords, summaries, or full transcriptions) to their own video, effectively exfiltrating the information. Commit aa2c46a806960a0006105df47765913394eec142 contains a patch.
