CVE-2026-19945: Themeum Wp Crowdfunding

Medium severity, CVSS 6.4. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Themeum Wp Crowdfunding: up to and including 2.2.1
