CVE-2026-3357

Estado: AnalizadaAlta (8.8)—

IBM Langflow Desktop 1.6.0 through 1.8.2 Langflow could allow an authenticated user to execute arbitrary code on the system, caused by an insecure default setting which permits the deserialization of untrusted data in the FAISS component.

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 CVSS AV:N/AC:L/PR:L sin UI:R indica acceso remoto con autenticación; CWE-502 (deserialización insegura) permite ejecución de código arbitrario. PR:L sugiere T1210 (servicios remotos con privilegios). Impacto: ejecución de comandos (T1059) y potencial escalada (C:H/I:H/A:H como root/administra

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.
