CVE-2026-63281Network attack vector

Stored script execution via unescaped condition summaries

Published Jul 22, 2026 · Updated Jul 22, 2026

Stored XSS in affected Regular Labs Joomla extensions allows attackers to execute script when administrators view condition summaries. Advanced Module Manager 1.0.0 through 11.0.1, Conditional Content 1.0.0 through 6.0.0, Content Templater Pro 1.0.0 through 13.0.0, and ReReplacer Pro 1.0.0 through 15.0.3 render stored condition values as HTML or JavaScript in administrator summaries without neutralization.
