Authenticated stored XSS via unsanitized SVG output
Published Jul 20, 2026 · Updated Jul 20, 2026
Stored XSS in ThemeXpert Quix Page Builder 1.0 through 6.2.0 allows remote authenticated users to inject scripts into Joomla pages. The extension renders builder-controlled output without escaping and accepts SVG content without sanitization, so injected code is stored with the page. A builder account is required, and the script executes for any visitor or administrator who views the affected page.
