CVE-2026-7803

Estado: AnalizadaCrítica (9.8)—

IBM Langflow OSS 1.0.0 through 1.10.0 could allow arbitrary code execution due to improper validation of flow nodes with missing or empty component type fields.

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/AC:L/PR:N/UI:N indica explotación remota sin privilegios (T1190). Validación impropia de componentes permite ejecución arbitraria de código en el servidor Langflow.

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.
