Stored XSS via unescaped shortcode class attribute
Published Oct 22, 2025 · Updated Oct 22, 2025
Stored XSS in DMB Web Designs Simple Business Data 1.0.1 and earlier allows remote authenticated users to inject scripts via shortcode attributes. The simple_business_data shortcode inserts its type attribute directly into an HTML class attribute without sanitization or output escaping. Contributor-level access is required, and the stored script executes in a visitor's browser when the injected page is opened, enabling page-context data access or modification.
