CVE-2026-17161Network attack vector

Contributor-level stored XSS via filterMobileText attribute breakout

Published Jul 29, 2026 · Updated Jul 29, 2026

Stored XSS in WPXPO WowStore 4.4.24 and earlier allows remote authenticated users to inject scripts through filterMobileText. The plugin stores an attribute-breakout payload as JSON in a Gutenberg block delimiter comment that wp_kses_post preserves, then emits it through the server-side render callback without sufficient output escaping. Contributor-level access is required, and the persisted script executes in the browser of anyone visiting the injected page, enabling actions within that browser session.
