CVE-2024-24815

Estado: ModificadaMedia (6.1)—

CKEditor4 is an open source what-you-see-is-what-you-get HTML editor. A cross-site scripting vulnerability has been discovered in the core HTML parsing module in versions of CKEditor4 prior to 4.24.0-lts. It may affect all editor instances that enabled full-page editing mode or enabled CDATA elements in Advanced Content Filtering configuration (defaults to `script` and `style` elements). The vulnerability allows attackers to inject malformed HTML content bypassing Advanced Content Filtering mechanism, which could result in executing JavaScript code. An attacker could abuse faulty CDATA content detection and use it to prepare an intentional attack on the editor. A fix is available in version 4.24.0-lts.

Se ha descubierto una vulnerabilidad de cross-site scripting en el módulo principal de análisis HTML en versiones de CKEditor4 anteriores a la 4.24.0-lts. Puede afectar a todas las instancias del editor que habilitaron el modo de edición de página completa o habilitaron elementos CDATA en la configuración de filtrado de contenido avanzado (los elementos predeterminados son `script` y `style`). La vulnerabilidad permite a los atacantes inyectar contenido HTML con formato incorrecto sin pasar por el mecanismo de filtrado de contenido avanzado, lo que podría resultar en la ejecución de código JavaScript. Un atacante podría abusar de la detección de contenido CDATA defectuosa y utilizarla para preparar un ataque intencional al editor. Hay una solución disponible en la versión 4.24.0-lts."
