CVE-2026-58574Network attack vector

Unauthenticated filesystem disclosure via management interface

Published Aug 31, 2026 · Updated Aug 31, 2026

Missing authentication in Dell PowerStore 4.1.x and 4.3.x allows remote attackers to read appliance filesystem data through the management interface. Dell identifies the restricted management interface as the affected locus but does not disclose the request, endpoint, or authentication check that is missing. Network access to that interface is required; exposed internal files can include credentials that grant full administrative access to the array.
