Descriptions

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in ibericode HTML Forms allows Stored XSS.This issue affects HTML Forms: from n/a through 1.3.28.

Vulnerabilidad de neutralización incorrecta de la entrada durante la generación de páginas web ('cross-site Scripting') en ibericode HTML Forms permite almacenar XSS. Este problema afecta a HTML Forms: desde n/a hasta 1.3.28.

The HTML Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.3.28 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
