CVE-2026-92378

Estado: AplazadaMedia (4.1)—

A session management vulnerability exists in the Legacy UI Reduced Function Login feature of NT-ware uniFLOW Online. Under specific timing conditions during Service Offline Emergency Mode, a previously authenticated session may be retained after logout, which could allow a subsequent user to be authenticated as the previous user and gain unauthorised limited access to device functionality.

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).
