What is CVE-2026-19945?
CVE-2026-19945 is a medium-severity cross-site scripting vulnerability in themeum WP Crowdfunding, published on 9 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
