AI Analysis
Technical Summary
CVE-2026-66916 describes an improper access control vulnerability (CWE-284) in the JoomGallery extension for Joomla. Specifically, when a gallery category is password-protected, the HTML view correctly enforces the password gate, but the JSON view (accessed via format=json) bypasses this check entirely. This allows unauthenticated users to access the contents of password-protected categories via the JSON endpoint in affected versions 4.0.0 through 4.3.0.
Potential Impact
An unauthenticated attacker can bypass password protection on gallery categories by requesting the JSON view, potentially exposing sensitive gallery content that should be restricted. This undermines the intended access control mechanism for password-protected categories.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch is indicated in the provided data. Until a patch is available, consider restricting access to the JSON view or disabling it if possible to prevent unauthorized access.
