Descriptions

The Interactive Contact Form and Multi Step Form Builder WordPress plugin before 3.4 does not sanitise and escape some parameters, which could allow unauthenticated users to perform Cross-Site Scripting attacks

El complemento Interactive Contact Form and Multi Step Form Builder de WordPress anterior a 3.4 no sanitiza ni escapa a algunos parámetros, lo que podría permitir a usuarios no autenticados realizar ataques de Cross-Site Scripting

The Funnelforms Free plugin for WordPress is vulnerable to Stored Cross-Site Scripting via form submission answers in versions up to, and including, 3.3.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
