CVE-2026-56453Network attack vector

Account takeover via manipulated HTTP responses

Published Jul 16, 2026 · Updated Jul 16, 2026

Authentication bypass in HCL DFX Analytics 3.0 and earlier allows remote authenticated users to take over targeted accounts. HCL describes interception and alteration of server HTTP responses before client processing but does not identify the affected endpoint or the exact operation that trusts the altered authentication data. Exploitation requires low-privilege access, user interaction, and high-complexity response interception; successful manipulation grants unauthorized access to the targeted account.
