CVE-2026-42516Network attack vector

Patient-account access via encoded parameter manipulation

Published Apr 29, 2026 · Updated Apr 29, 2026

Broken access control in C-DAC e-Sushrut HMIS allows remote authenticated users to access other patients' accounts via crafted URLs. The resource-access path trusts encoded request-URL parameters without a sufficient authorization check tying the requested account to the caller. A valid e-Sushrut account and network reachability are required; exploitation exposes patient account data and permits limited changes.
