Estado: ModificadaAlta (7.5)—

En Apache NiFi, en versiones anteriores a la 0.7.2 y versiones 1.x, anteriores a la 1.1.2, en un entorno de clúster, si se copia la petición de un usuario anónimo a otro nodo, se utiliza la identidad del nodo que la originó en lugar de la del usuario "anónimo".

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).
