Joomla CMS can be tricked into contacting internal servers

CVE-2026-92222 · published 1 month ago
Summary

Versions of Joomla! CMS from 4.0.0 up to 5.4.8 and 6.0.0 through 6.1.3 allow specially crafted URLs in core features to bypass address checks. This could let an attacker make the website reach internal network resources or services, potentially exposing sensitive data. Update Joomla to the latest patched release or apply the vendor's recommended configuration changes to validate external requests.

What to do
