DescriptionCVE.org

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 fails to check user authorization in the PlayerSkins mediaSession.json.php endpoint before returning video metadata. Unauthenticated attackers can request the endpoint with a video ID parameter to retrieve password-protected video titles and owner email addresses without authentication.

AnalysisAI

Missing authorization in the PlayerSkins mediaSession.json.php endpoint of WWBN AVideo exposes protected video metadata to unauthenticated network attackers. By supplying a video ID parameter to this endpoint, any remote attacker can retrieve the title and owner email address of password-protected videos without providing credentials, defeating the access-control intent of password protection. …

Vulnerability AssessmentAI

Exploitation No authentication is required - exploitation targets default AVideo deployments with no special server configuration required beyond the presence of password-protected videos. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) correctly reflects frictionless unauthenticated network exploitation with no special attack requirements, while the VC:L score appropriately caps the impact at low confidentiality - leaked data is limited to video titles and owner email addresses, not video content or credentials. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Update WWBN AVideo to a commit after c3edcc274c389816d434acadac07ee78eaf330c1 once a patched release is available per the GitHub Security Advisory GHSA-g79r-wg9m-3fh3 (https://github.com/WWBN/AVideo/security/advisories/GHSA-g79r-wg9m-3fh3). … Detailed patch versions, workarounds, and compensating controls in full report.
