CVE-2026-48956 · Severity: info · CVSS 6.4 · Published 2026-07-07

Joomla! CMS, a popular platform for building and managing websites, contains a security flaw in how it handles access permissions for site modules. An attacker with high-level administrative privileges can bypass intended restrictions to view a list of installed modules on the public-facing side of the website. While this does not directly allow for data theft, it exposes information about the site's configuration that could be used to plan further attacks.
