CVE-2026-21994Network attack vector

Unauthenticated takeover via hardcoded Flask signing key

Published Mar 17, 2026 · Updated Mar 17, 2026

Hardcoded secret in Oracle Edge Cloud Infrastructure Designer and Visualisation Toolkit 0.3.0 allows remote attackers to gain control. The okitclassic/okitserver/config.py module assigns every installation the same static Flask SECRET_KEY, making signed authentication state forgeable. Remote attackers need unauthenticated HTTP access to the embedded web service; successful exploitation grants control of the toolkit and its data.
