What the vulnerability does

01Description

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.

Explanation of Vulnerability in Simple Terms

02Summary

GiveWP versions up to 4.14.4 contain a cross-site scripting vulnerability that allows authenticated users with low privileges to inject malicious scripts. The vulnerability has a changed scope, meaning the impact can extend beyond the vulnerable component to affect other users or site functionality. Site administrators should update to a version newer than 4.14.4 to remediate this issue.
