CVE-2026-9205

Estado: AnalizadaCrítica (9.8)—

IBM Langflow OSS contains a weak cryptographic key derivation vulnerability in the ensure_fernet_key() function.

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:3.1/AV:N/AC:L/PR:N/UI:N apunta a T1190. CWE-338 (débil derivación criptográfica) en clave Fernet permite al atacante remoto derivar claves débiles, logrando ejecución de código, acceso a datos y manipulación de información.

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.
