Vulnerabilidad · Publicado 21/08/2026
El complemento WPForms Pro para WordPress es vulnerable a inyección de scripts almacenados en campos de texto simple y párrafo (versiones hasta 2.0.0.2) debido a sanitización insuficiente. Atacantes no autenticados pueden inyectar código malicioso que se ejecuta cuando usuarios acceden a páginas comprometidas. Este riesgo es alta para sitios comerciales, de servicios y gobierno en LATAM que dependen de formularios para captura de datos.
The WPForms Pro plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Single Line Text and Paragraph Text Field Values in all versions up to, and including, 2.0.0.2 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. The exploit relies on the plugin's own wp_kses_allowed_html filter widening the 'post' allowlist to permit iframe elements with a data-src attribute, which is not on WordPress's URI-attribute sanitization list, allowing a javascript: URI stored in data-src to survive kses processing and subsequently be promoted to a live src attribute by the bundled admin script view-entry.min.js.
