CVE-2026-71177Network attack vector

Session theft via unrestricted interface framing

Published Sep 23, 2026 · Updated Sep 23, 2026

UI-layer restriction failure in Dell Secure Connect Gateway Policy Manager before 5.36.00.16 allows remote authenticated users to steal sessions. Dell has not disclosed which interface response omits or misconfigures frame restrictions, so the specific affected page and header remain unknown. Low-privileged account access is required; successful exploitation exposes a session and enables privilege elevation within the management interface.
