What the vulnerability does
01Description
The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the donor notes parameter in all versions up to, and including, 4.5.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with GiveWP worker-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Additionally, they need to trick an administrator into visiting the legacy version of the site.
Explanation of Vulnerability in Simple Terms
02Summary
GiveWP versions up to 4.5.0 contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability requires user interaction—typically a victim clicking a crafted link—and can affect other users on the site. An attacker with low-level access can inject code that steals session tokens or performs actions on behalf of other users.
