Authenticated information tampering via user-controlled key

Published Aug 26, 2026 · Updated Aug 27, 2026

Authorization bypass in Dell PowerProtect One 20.1.0.0 and earlier allows remote authenticated users to tamper with information. Dell has not published the affected request or how its user-controlled key bypasses the corresponding authorization check. Low-privileged network access is required, and the documented consequence is integrity-only modification rather than disclosure or service interruption.
