Executive brief
GiveWP is a popular WordPress plugin that allows organizations to create donation forms and fundraising campaigns. The plugin contains a vulnerability in how it processes donation form shortcodes, allowing authorized users with Contributor-level permissions to inject malicious scripts. When other users view pages containing injected content, the scripts execute in their browsers, potentially capturing sensitive information or performing unauthorized actions on their behalf.
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.
