WWBN AVideo Missing Authorization via video_from_program API

Published Sep 12, 2026 CVSS 4.0 · 6.9 Medium EPSS < 1% KEV · Not listed
Description
WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 fails to validate playlist ownership in the video_from_program API endpoint, allowing unauthenticated access to private playlist contents. Attackers can query the API without authentication to enumerate private playlist names, owner information, and video titles including password-protected content.

Analysis

AI-generated

Technical impact

WWBN AVideo allows an attacker to request the video_from_program API without any authentication, bypassing ownership checks and exposing the contents of private playlists. The attacker can enumerate playlist names, discover owner identities, and retrieve video titles, including those in password-protectedCWE-862). The primary consequence is confidential information disclosure of protected content, potentially enabling further exploitation if additional weaknesses exist.

Affected Systems

The vulnerability affects installations of the WWBN AVideo. All deployed versions that include the unpatched commit c3edcc274c389816d434acadac07ee are vulnerable. No specific version list is provided, so any instance that uses the affected code should be considered at risk.

Risk and Exploitability

This missing authorization flaw (CWE-862) carries a CVSS score of 6.9, indicating moderate1% indicates only a very low but nonzero probability of exploitation. The vulnerability is not listed in the CISA KEV catalog. Attackers can leverage the open API to gather sensitive information without any user interaction or authentication, making exploitation trivial for automated scanners or malicious actors who discover the endpoint. Because the API returns metadata about private collections, the impact is primarily confidentiality breach with potential for further exploitation if additional weaknesses exist.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Deploy the latest patched release of AVideo that implements ownership validation on the video_from_program endpoint, or apply the commit that corrects the authorization logic.
  • Restrict network access to the AVideo API by deploying firewall rules or VPN segmentation so that only authorized internal systems can reach the endpoint.
  • Review and reconfigure playlist permissions, removing unnecessary private collections or applying additional encryption or access controls to mitigate potential data leaks.
