The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'give_form' shortcode in all versions up to, and including, 4.14.4. This is due to insufficient input sanitization and output escaping on the continue_button_title and display_style shortcode attributes, which are passed through sanitize_text_field() but not properly escaped when output in HTML data attributes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
