CVE-2026-35147Network attack vector

Unauthenticated API access via missing authentication-status verification

Published Jul 16, 2026 · Updated Jul 16, 2026

Broken authentication in HCL DFXServer 2.5 and earlier allows remote attackers to perform unauthorized API actions without credentials. The request path for specific API endpoints dispatches calls without first verifying the caller's authentication status; HCL has not named the endpoints. No credentials or user interaction are required; exposed endpoints permit unauthorized data access and limited modification, but not service interruption.
