CVE-2026-74774Network attack vector

Protection bypass via improper certificate validation

Published Aug 26, 2026 · Updated Aug 26, 2026

Improper certificate validation in Dell PowerProtect One before 20.3.0.0 allows remote attackers to bypass a protection mechanism. Dell has not disclosed which certificate-handling component accepts an invalid certificate or which validation check it omits. Exploitation requires no authentication but has high complexity, and the published assessment limits the reported consequence to confidentiality loss rather than data modification or service interruption.
