CVE-2026-42862

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 tool update endpoint of FlowiseAI. The endpoint allows authenticated users to modify server-controlled properties such as workspaceId, createdDate, and updatedDate when updating a tool resource. Due to missing server-side validation and authorization checks, an attacker can manipulate the workspaceId field and reassign tools to arbitrary workspaces. This breaks tenant isolation in multi-workspace environments. 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.

Vulnerabilidad de asignación masiva en endpoint de actualización que requiere autenticación (PR:L). Atacante modifica propiedades de servidor (workspaceId) para reasignar recursos y quebrantar aislamiento entre espacios de trabajo, alterando datos de configuración y asignaciones de acceso.

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 herramientas de FlowiseAI. El endpoint permite a los usuarios autenticados modificar propiedades controladas por el servidor, como workspaceId, createdDate y updatedDate, al actualizar un recurso de herramienta. Debido a la falta de validación del lado del servidor y comprobaciones de autorización, un atacante puede manipular el campo workspaceId y reasignar herramientas a espacios de trabajo arbitrarios. Esto rompe el aislamiento de inquilinos en entornos multi-espacio de trabajo. Este problema ha sido parcheado en la versión 3.1.2."
