CVE-2025-46235Network attack vector

Stored XSS via undisclosed Post Grid flaw

Published Apr 22, 2025 · Updated May 12, 2026

Stored XSS in the Post Grid block of SKT Blocks 2.0 and earlier allows remote authenticated users to execute script in visitors' browsers. The upstream changelog identifies the Post Grid block, but the CNA record and its sole advisory do not disclose the input field, code locus, or failed sanitization or escaping operation. Low-privileged WordPress access and interaction by a visitor who renders the stored block content are required; execution occurs in that visitor's browser.
