What is CVE-2026-60034?

The JMedia extension for Joomla is susceptible to a stored cross-site scripting (XSS) vulnerability due to improper sanitization of SVG uploads. This flaw allows malicious users to upload specially crafted SVG files, which can execute arbitrary scripts in the context of other users' sessions. When these SVG files are served without the appropriate 'nosniff' header, it could lead to reflected and stored XSS attacks, putting users' data at risk and potentially compromising the integrity of the website.

Affected Version(s)
