CVE-2025-12823Network attack vector

Stored script execution via unescaped shortcode attributes

Published Nov 18, 2025 · Updated Nov 18, 2025

Stored XSS in Shaun Scovil CSV to SortTable 4.2 and earlier allows remote authenticated users to inject scripts via csv shortcode attributes. The csv shortcode handler accepts user-controlled attributes and renders them into generated table markup without sufficient sanitization or context-appropriate escaping. Contributor-level access is required to save the shortcode in a post or page, and the stored script executes whenever a user visits that content.
