CVE-2023-23627

Sanitize is an allowlist-based HTML and CSS sanitizer. Versions 5.0.0 and later, prior to 6.0.1, are vulnerable to Cross-site Scripting. When Sanitize is configured with a custom allowlist that allows `noscript` elements, attackers are able to include arbitrary HTML, resulting in XSS (cross-site scripting) or other undesired behavior when that HTML is rendered in a browser. The default configurations do not allow `noscript` elements and are not vulnerable. This issue only affects users who are using a custom config that adds `noscript` to the element allowlist. This issue has been patched in version 6.0.1. Users who are unable to upgrade can prevent this issue by using one of Sanitize's default configs or by ensuring that their custom config does not include `noscript` in the element allowlist.

Summary
  • (es) Sanitize es un desinfectante de HTML y CSS basado en listas de permitidos. Las versiones 5.0.0 y posteriores, anteriores a la 6.0.1, son vulnerables a cross-site scripting. Cuando Sanitize se configura con una lista de permitidos personalizada que permite elementos "noscript", los atacantes pueden incluir HTML arbitrario, lo que genera XSS (scripting entre sitios) u otro comportamiento no deseado cuando ese HTML se representa en un navegador. Las configuraciones predeterminadas no permiten elementos "noscript" y no son vulnerables. Este problema solo afecta a los usuarios que utilizan una configuración personalizada que agrega "noscript" a la lista de elementos permitidos. Este problema se solucionó en la versión 6.0.1. Los usuarios que no pueden actualizar pueden evitar este problema usando una de las configuraciones predeterminadas de Sanitize o asegurándose de que su configuración personalizada no incluya "noscript" en la lista de elementos permitidos.
