CVE-2026-27126

Craft is a content management system (CMS). In versions 4.5.0-RC1 through 4.16.18 and 5.0.0-RC1 through 5.8.22, a stored Cross-site Scripting (XSS) vulnerability exists in the `editableTable.twig` component when using the `html` column type. The application fails to sanitize the input, allowing an attacker to execute arbitrary JavaScript when another user views a page with the malicious table field. In order to exploit the vulnerability, an attacker must have an administrator account, and `allowAdminChanges` must be enabled in production, which is against Craft's security recommendations. Versions 4.16.19 and 5.8.23 patch the issue.

Summary
  • (es) Craft es un sistema de gestión de contenido (CMS). En las versiones 4.5.0-RC1 a 4.16.18 y 5.0.0-RC1 a 5.8.22, existe una vulnerabilidad de cross-site scripting (XSS) almacenado en el componente 'editableTable.twig' al usar el tipo de columna 'html'. La aplicación no sanitiza la entrada, permitiendo a un atacante ejecutar JavaScript arbitrario cuando otro usuario ve una página con el campo de tabla malicioso. Para explotar la vulnerabilidad, un atacante debe tener una cuenta de administrador, y 'allowAdminChanges' debe estar habilitado en producción, lo cual va en contra de las recomendaciones de seguridad de Craft. Las versiones 4.16.19 y 5.8.23 parchean el problema.
