CVE-2026-2358
The WP ULike plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `[wp_ulike_likers_box]` shortcode `template` attribute in all versions up to, and including, 5.0.1. This is due to the use of `html_entity_decode()` on shortcode attributes without subsequent output sanitization, which effectively bypasses WordPress's `wp_kses_post()` content filtering. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The post must have at least one like for the XSS to render.

Esto se debe al uso de 'html_entity_decode()' en los atributos del shortcode sin una posterior sanitización de la salida, lo que efectivamente omite el filtrado de contenido 'wp_kses_post()' de WordPress. Esto hace posible que atacantes autenticados, con acceso de nivel Colaborador o superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada. La publicación debe tener al menos un 'me gusta' para que el XSS se renderice."
