Description
A vulnerability in the JoomGallery extension for Joomla allows unauthenticated attackers to bypass password protection on gallery categories via the JSON view. While the HTML view enforces password protection correctly, the JSON format view does not check the password, exposing protected category data. This affects versions 4.0.0 through 4.3.0 of JoomGallery.

Technical Analysis
CVE-2026-66916 is an improper access control vulnerability (CWE-284) in the JoomGallery extension for Joomla. The flaw exists because the JSON view of gallery categories does not enforce password protection, unlike the HTML view. This allows unauthenticated users to access password-protected gallery categories by requesting data in JSON format. The issue affects JoomGallery versions from 4.0.0 up to and including 4.3.0.
Potential Impact
An attacker can bypass password protection on gallery categories by accessing the JSON view, potentially exposing sensitive gallery content without authentication. This undermines the intended access control mechanism for password-protected categories.
Mitigation Recommendations
No patch or official fix is currently documented. Users should monitor the vendor advisory for updates. Until a fix is available, consider disabling the JSON view or restricting access to it via other means to prevent unauthorized access.
