CVE-2026-90971Network attack vector

Credential theft via VMware synchronization SSRF

Published Sep 15, 2026 · Updated Sep 15, 2026

SSRF in Devolutions Server 2026.2.16 and earlier allows remote authenticated users to steal credentials via VMware synchronization. Datacenter discovery accepts a crafted connection definition and sends server-side requests to its supplied endpoint without adequately restricting the destination. Low-privileged access is required; successful requests can expose other users' credentials or reach internal services and cloud-metadata endpoints.
