CVE-2026-66690

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 allows authenticated attackers with Contributor-level access or above to inject arbitrary web scripts that execute when a user accesses an injected page.

The GiveWP plugin version 4.16.3 and earlier is vulnerable to unauthenticated Cross Site Request Forgery (CSRF). An attacker can trick an administrator into performing unwanted actions.

Deserialization of Untrusted Data vulnerability in Liquid Web / StellarWP GiveWP allows Object Injection. This issue affects GiveWP from n/a through 4.16.7.1.

Broken Access Control vulnerability in GiveWP versions up to 4.16.5.1. The attack does not require authentication.

Broken Access Control vulnerability in GiveWP versions earlier than 4.16.6. The attack does not require authentication.

Donor Cross Site Scripting (XSS) in GiveWP < 4.16.6 versions.

Unauthenticated Broken Access Control vulnerability in GiveWP plugin versions prior to 4.16.6.

The GiveWP WordPress plugin before version 4.16.3 does not properly restrict access to a REST API endpoint that returns recurring-donation records. This allows unauthenticated users to retrieve information about anonymous recurring donors, including their name and subscription details.

The GiveWP WordPress plugin before version 4.16.3 does not restrict the set of available payment gateways to those enabled by the administrator, deriving it in part from request input. This allows unauthenticated users to complete donations through a payment gateway the administrator has disabled.

XSS vulnerability in GiveWP up to version 4.16.3. An unauthenticated attacker can inject malicious JavaScript.
