CVE-2026-35179: CWE-862: Missing Authorization in WWBN AVideo
WWBN AVideo is an open source video platform. In versions 26.0 and prior, the SocialMediaPublisher plugin exposes a publishInstagram.json.php endpoint that acts as an unauthenticated proxy to the Facebook/Instagram Graph API. The endpoint accepts user-controlled parameters including an access token, container ID, and Instagram account ID, and passes them directly to the Graph API via InstagramUploader::publishMediaIfIsReady(). This allows any unauthenticated user to make arbitrary Graph API calls through the server, potentially using stolen tokens or abusing the platform's own credentials.
AI Analysis
Technical Summary
CVE-2026-35179 is a missing authorization vulnerability (CWE-862) in WWBN AVideo (<= 26.0) within the SocialMediaPublisher plugin. The publishInstagram.json.php endpoint does not require authentication and forwards user-supplied parameters, including access tokens and Instagram account identifiers, directly to the Facebook/Instagram Graph API via InstagramUploader::publishMediaIfIsReady(). This design flaw enables unauthenticated attackers to perform arbitrary Graph API calls through the server, potentially leveraging stolen tokens or abusing the platform's own credentials to interact with Instagram or Facebook services.
Potential Impact
The vulnerability allows unauthenticated attackers to abuse the platform as a proxy to the Facebook/Instagram Graph API, potentially enabling unauthorized actions such as posting or modifying content if valid access tokens are supplied. While the CVSS score indicates a medium severity with no direct confidentiality or availability impact, the integrity of Instagram or Facebook interactions via the platform can be compromised. There are no reports of active exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider restricting access to the vulnerable endpoint or disabling the SocialMediaPublisher plugin if feasible. Monitoring for unusual API activity related to Instagram or Facebook integrations is advisable. Avoid exposing the publishInstagram.json.php endpoint to untrusted users.
