Authenticated device-information disclosure via devices REST endpoint
Published May 12, 2026 · Updated May 12, 2026
Incorrect authorization in PowerSYSTEM Center 2020 5.11.x through 5.28.x allows remote authenticated users to read restricted device information. The devices REST API endpoint returns information to accounts whose operational permissions do not authorize that access; CISA does not disclose the internal authorization logic. Reachability requires a low-privilege account on an adjacent network, and the reported consequence is read-only disclosure.
