CVE-2026-60029Network attack vector

Authenticated stored XSS via id/class field breakout

Published Jul 20, 2026 · Updated Jul 20, 2026

Stored XSS in ThemeXpert Quix Page Builder Pro 1.0 through 6.2.0 allows remote authenticated users to inject script into public pages. The builder accepts crafted id or class field values that break out of their HTML attributes and renders them without sufficient neutralization. Builder access is required, and loading an affected published page executes the stored script in a public visitor's browser, enabling page modification and access to browser-visible data.
