CVE-2025-13747Network attack vector

Stored XSS via shortcode regex bypass

Published Dec 12, 2025 · Updated Dec 12, 2025

Stored XSS in ice00 NewStatPress 1.4.3 and earlier allows remote authenticated users to inject scripts through shortcode attributes. The nsp_shortcode function applies an incomplete regular-expression filter to user-supplied attributes and emits surviving markup without sufficient output escaping. Contributor-level access is required to store the payload in a page; the script executes in each visitor's browser when the page opens.
