CVE-2026-19945

The WP Crowdfunding plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'first name' parameter in all versions up to, and including, 2.2.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. An administrator viewing any user's profile via the ?show user id= parameter will render the attacker's stored payload in the admin's browser session, enabling cross-privilege script execution.
