Sensitive session data exposure via persistent cookies
Published Feb 3, 2026 · Updated Feb 3, 2026
Persistent-cookie exposure in HCL AION 2.0 allows attackers to obtain sensitive session data through a compromised browser cookie. The application’s cookie handling stores sensitive session information beyond the browser session instead of limiting it to a nonpersistent cookie. The reported attack requires high privileges, user interaction, and interception or compromise of the cookie; HCL does not identify the cookie or stored data.
