What is CVE-2026-33507?

WWBN AVideo, an open source video platform, presents a vulnerability that enables admin users to upload unverified plugin ZIP files through the objects/pluginImport.json.php endpoint. This endpoint lacks CSRF protection, allowing an attacker to exploit it by crafting a malicious page. If an authenticated admin visits the page, the attacker can silently install a malicious plugin containing PHP code—potentially leading to Remote Code Execution on the server. It is recommended to upgrade to patched versions to mitigate this risk.

Affected Version(s)

AVideo <= 26.0
