Stored XSS via unescaped spacing shortcode attribute
Published Jan 7, 2026 · Updated Jan 7, 2026
Stored XSS in the Niche Hero WordPress plugin 1.0.5 and earlier allows remote authenticated users to inject scripts through the nh_row shortcode. The nh_row handler places the untrusted spacing attribute into generated page markup without sanitizing the value or escaping its output. Contributor-level access is sufficient, and the stored script executes in a visitor's browser whenever the affected page is rendered.
