What is CVE-2026-35179?

The SocialMediaPublisher plugin in WWBN AVideo versions 26.0 and earlier contains a vulnerability that exposes an unauthenticated endpoint, publishInstagram.json.php. This endpoint allows any unauthenticated user to bypass access controls and perform arbitrary calls to the Facebook/Instagram Graph API. It accepts user-controlled parameters, including access tokens and account IDs, which are passed directly to the Graph API, potentially enabling attackers to exploit compromised tokens or misuse credentials. This raises significant security concerns regarding unauthorized access and actions on Instagram accounts.

Affected Version(s)
