WWBN AVideo Missing Authorization in ImageGallery list.json.php

Published Sep 12, 2026 CVSS 4.0 · 6.9 Medium EPSS < 1% KEV · Not listed

Description

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 fails to validate user permissions in the ImageGallery list.json.php endpoint, allowing unauthenticated access to list gallery files. Attackers can retrieve filenames and URLs of password-protected image galleries by directly accessing the endpoint, then fetch the exposed files without authentication.

Analysis

Technical impact

The vulnerability resides in WWBN AVideo’s ImageGallery list.json.php endpoint, where the application fails to validate user permissions, enabling an unauthenticated user to read the list of filenames and URLs for galleries. This is an instance of CWE‑200 (Information Exposure) and results in a confidentiality impact, exposing the location of private image files that were intended to be protected.

Affected Systems

Any deployment of WWBN AVideo before commit c3edcc274c389816d434acadac07ee78eaf330c1 that exposes the ImageGallery list.json.php endpoint to the public web is affected. This includes installations that have not applied the patch for the missing authorization check.

Risk and Exploitability

The CVSS score of 6.9 indicates a moderate to high severity, and the EPSS score of less than 1% suggests a low probability of exploitation. The vulnerability is not listed in the CISA KEV catalogue. Attackers can reach the compromised endpoint over the web, retrieve file paths and URLs, representing a direct confidentiality breach for any gallery that was intended to be password‑protected.
