CVE-2026-44409

Information disclosure via misconfigured access controls

Published May 22, 2026 · Updated May 22, 2026

Information disclosure in ZTE U60 Pro MU5250 firmware BD_FLYMODEMMU5250V1.0.0B27 allows remote authenticated users to read protected information. An improperly configured access-control mechanism permits unauthorized retrieval, but ZTE has not identified the affected interface, request, or data fields. Exploitation requires low privileges and adjacent-network access; the published impact is limited to confidentiality, with no reported data modification or service interruption.
