CVE-2026-10864
MISP Dashboard widget field selection may expose restricted user and organisation data
Description
A vulnerability in the MISP dashboard widgets allowed an authenticated user to manipulate the fields option and influence which fields were returned by the New Users and New Organisations widgets. In some cases, requesting a field set that became empty after validation or redaction could cause the underlying query to fall back to returning unintended model fields. For the New Users widget, this could allow a non-site-admin user to obtain user e-mail addresses even when user e-mail disclosure was disabled by configuration. For the New Organisations widget, crafted field selection could similarly result in unintended organisation fields being included in the dashboard response. The issue was caused by applying field filtering and redaction in a way that could leave the selected field list empty. The patch ensures that the allowed field list is built safely, that restricted fields such as user e-mail addresses are removed before user-supplied field selection is processed, and that an empty field selection falls back only to the permitted default fields. Impact: An authenticated low-privileged user with access to the affected dashboard widgets may be able to disclose restricted user or organisation metadata, including user e-mail addresses depending on configuration.

Action Type Old Value New Value Added Translation Title: MISP Dashboard, Description: Una vulnerabilidad en los widgets del panel de control de MISP permitía a un usuario autenticado manipular la opción de campos e influir en qué campos eran devueltos por los widgets de Nuevos Usuarios y Nuevas Organizaciones. En algunos casos, solicitar un conjunto de campos que quedaba vacío después de la validación o redacción podría hacer que la consulta subyacente recurriera a devolver campos de modelo no deseados. Para el widget de Nuevos Usuarios, esto podría permitir a un usuario no administrador del sitio obtener direcciones de correo electrónico de usuario incluso cuando la divulgación de correo electrónico de usuario estaba deshabilitada por configuración. Para el widget de Nuevas Organizaciones, una selección de campos elaborada podría resultar de manera similar en campos de organización no deseados siendo incluidos en la respuesta del panel de control. El problema fue causado por aplicar el filtrado y la redacción de campos de una manera que podría dejar la lista de campos seleccionados vacía. El parche asegura que la lista de campos permitidos se construye de forma segura, que los campos restringidos, como las direcciones de correo electrónico de usuario, se eliminan antes de que se procese la selección de campos proporcionada por el usuario, y que una selección de campos vacía recurre solo a los campos predeterminados permitidos. Impacto: Un usuario autenticado con bajos privilegios con acceso a los widgets del panel de control afectados podría ser capaz de divulgar metadatos restringidos de usuario u organización, incluyendo direcciones de correo electrónico de usuario dependiendo de la configuración. -
