CVE-2026-33684: WWBN AVideo privilege escalation in signUp API

CVE-2026-33684 · Severity: medium · CVSS 5.3 · Published 2026-07-15

WWBN AVideo is an open-source platform used for hosting and streaming video content. A security flaw in the account registration process allows new users to grant themselves administrative-level permissions, such as the ability to upload videos, start live streams, and create meetings, without approval. This could lead to unauthorized use of server resources, the hosting of unvetted content, and the bypass of email verification requirements.

Technologies: wwbn/avideo (Packagist), WWBN AVideo. Vendors: Packagist, WWBN.

Technical details

A privilege escalation vulnerability exists in the `set_api_signUp` method within the API plugin of WWBN AVideo. The root cause is a failure to validate the `APISecret` before processing sensitive parameters such as `emailVerified`, `canUpload`, `canStream`, and `canCreateMeet`. While the code checks for either a valid `APISecret` or a solved CAPTCHA to allow registration, it fails to restrict the subsequent permission-setting logic to only those requests authenticated with the secret. An unauthenticated remote attacker can solve a CAPTCHA and submit a crafted POST request to `set.json.php` to register an account with elevated privileges. This allows attackers to bypass email verification and administrative restrictions on uploading or streaming. The issue is resolved in version 29.0.
