Contributor-level stored XSS via unescaped shortcode attributes
Published Nov 16, 2024 · Updated Apr 8, 2026
Stored XSS in the Steel WordPress plugin 1.3.0 and earlier allows remote authenticated users to inject scripts through the btn shortcode. The btn shortcode accepts user-supplied attributes without sufficient input sanitization and renders them without adequate output escaping. Contributor-level access is required, and the injected script executes when a visitor opens the affected page.
