This vulnerability (CVE-2026-48956) in Joomla! CMS involves an improper access check (CWE-284) that permits users to view a list of modules on the frontend interface. The flaw affects Joomla! CMS versions 4.0.0 through 5.4.6 and 6.0.0 through 6.1.1. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required, no user interaction, and low impact on confidentiality but high impact on security and integrity. The vulnerability is published and assigned but lacks a vendor-provided remediation or patch at this time.

The vulnerability allows unauthorized users to display a list of modules on the frontend, which could potentially expose sensitive configuration or module information. The CVSS score of 6.4 (medium severity) reflects a moderate risk, primarily due to improper access control. There are no known exploits in the wild currently.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or temporary workaround is provided, users should monitor Joomla! Project advisories for updates. Until a patch is available, restricting access to frontend module listings through configuration or access control settings may help reduce exposure.
