CVE-2026-42863

Estado: AnalizadaAlta (7.6)—

Flowise is a drag & drop user interface to build a customized large language model flow. Prior to version 3.1.2, a mass assignment vulnerability exists in the chatflow update endpoint of FlowiseAI. The endpoint allows clients to modify server-controlled properties such as deployed, isPublic, workspaceId, createdDate, and updatedDate when updating a chatflow object. Due to missing server-side validation and authorization checks, an authenticated user can manipulate internal attributes of a chatflow and reassign it to another workspace. This allows cross-workspace resource reassignment and unauthorized modification of deployment and visibility settings. This issue has been patched in version 3.1.2.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector AV:N + PR:L sin UI indican servicio remoto autenticado (T1210). Impactos: modificación de propiedades internas (T1565.002), cambio de visibilidad/permisos entre workspaces (T1078.001), escalada de privilegios de facto (T1548).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

Antes de la versión 3.1.2, existe una vulnerabilidad de asignación masiva en el endpoint de actualización de chatflow de FlowiseAI. El endpoint permite a los clientes modificar propiedades controladas por el servidor como deployed, isPublic, workspaceId, createdDate y updatedDate al actualizar un objeto chatflow. Debido a la falta de validación del lado del servidor y de comprobaciones de autorización, un usuario autenticado puede manipular atributos internos de un chatflow y reasignarlo a otro espacio de trabajo. Esto permite la reasignación de recursos entre espacios de trabajo y la modificación no autorizada de la configuración de despliegue y visibilidad. Este problema ha sido parcheado en la versión 3.1.2."
