CVE-2026-3750Public exploitNetwork attack vector

Authenticated SSRF via unchecked S3 endpoint

Published Mar 8, 2026 · Updated Mar 8, 2026

SSRF in ContiNew Admin 4.0, 4.1, and 4.2.0 allows remote authenticated users to make the server request attacker-chosen URLs. S3ClientFactory passes the storage endpoint to URI.create for S3 client configuration without restricting its destination. High-privilege storage-management access is required, and reachable internal services can receive requests from the application server.
