CVE-2025-13861

17.12.2025, 05:16

The HTML Forms  Simple WordPress Forms Plugin for WordPress is vulnerable to Unauthenticated Stored Cross-Site Scripting in all versions up to and including 1.6.0 due to insufficient sanitization of fabricated file upload field metadata before displaying it in the WordPress admin dashboard. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute whenever an administrator accesses the form submissions page.
