CVE-2026-60034Network attack vector

Authenticated stored XSS via unsanitized SVG uploads

Published Jul 20, 2026 · Updated Jul 20, 2026

Stored cross-site scripting in ThemeXpert JMedia 1.0 through 1.5.4 allows remote authenticated users to execute script via SVG uploads. The upload path accepts unsanitized SVG content and serves it without nosniff protection, causing browsers to interpret attacker-controlled markup as active content. High-privilege Joomla access is required; the script executes in the affected site's origin when the malicious SVG is served.
