CVE-2025-58983Network attack vector

Stored XSS via unfiltered post custom fields

Published Sep 9, 2025 · Updated Apr 28, 2026

Stored XSS in Stefano Lissa Include Me 1.3.2 and earlier allows remote authenticated users to inject script through post metadata. The shortcode renders a referenced post custom field without applying WordPress's unfiltered-HTML restriction, so stored markup reaches page output. Administrator-level privileges are required to store the payload, and another user's page view triggers it.
