CVE-2026-42518Network attack vector

Information disclosure via client-side AES keys

Published Apr 29, 2026 · Updated Apr 29, 2026

Information disclosure in previous versions of C-DAC e-Sushrut HMIS allows remote attackers to obtain AES keys from client-side JavaScript. The application places sensitive information and fixed AES encryption keys in JavaScript delivered to unauthenticated clients, making the secrets retrievable with the code. Network access to the application is sufficient to recover the keys and read protected data; no integrity change or service interruption is reported.
