CVE-2023-33860Network attack vector

Token disclosure via missing Secure cookie attribute

Published Jul 10, 2024 · Updated May 19, 2025

Sensitive-cookie exposure in IBM QRadar EDR 3.12 allows remote attackers to read authorization tokens or session cookies over HTTP. The web application creates authorization tokens or session cookies without the Secure attribute, so browsers can attach them to unencrypted HTTP requests. Exposure requires an affected browser to request an HTTP URL within the cookie's scope while an attacker can observe the network traffic.
