CVE-2026-35140Network attack vector

Session token exposure via missing Secure cookie flag

Published Jul 16, 2026 · Updated Jul 16, 2026

Missing Secure attributes on session cookies in HCL DFX Analytics 3.0 and earlier allow remote authenticated users to capture tokens over HTTP. The authentication flow sets session cookies without the Secure flag, so browsers can retransmit them over unencrypted HTTP connections. Exploitation requires low-privileged access, user interaction, and an unencrypted channel, exposing cookies, session tokens, or credentials.
