Technical details

The vulnerability is a Stored Cross-Site Scripting (XSS) flaw affecting the 'give_form' shortcode in versions up to 4.14.4. The root cause is insufficient input sanitization and output escaping of the 'continue_button_title' and 'display_style' shortcode attributes. Although these attributes are passed through sanitize_text_field(), the sanitized values are not properly escaped when output in HTML data attributes, allowing script injection. Attack requires Contributor-level WordPress access or above. An authenticated attacker can inject arbitrary JavaScript that persists in the page and executes in the browsers of all subsequent visitors. Patches are available in versions after 4.14.4.
