AI-suggested
Until an official fix is available, administrators should limit access to the form submissions page to trusted users only and consider disabling or removing the vulnerable plugin. Monitoring for suspicious activity related to admin dashboard access is advisable. Avoid interacting with untrusted form submissions or file uploads that could contain malicious metadata.
Description
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.
