CVE-2025-43992Network attack vector

Unauthenticated data access via assumed-immutable replication data

Published May 11, 2026 · Updated May 11, 2026

Authentication bypass in Dell ECS 3.8.1.0 through 3.8.1.7 and ObjectScale before 4.3.0.0 allows remote attackers to access data in transit. Geo replication treats security-relevant data as immutable during authentication, but Dell has not identified the affected field or validation path. Remote access to a Geo-replication path is required, and the disclosed consequence is unauthorized access to data in transit.
