Session-data disclosure via missing cookie Path
Published Jul 21, 2026 · Updated Jul 21, 2026
Cookie scope weakness in HCL MyCloud 10.8.2 allows remote authenticated users to access session data or authentication tokens. HCL has not identified which cookie lacks Path or explained how its scope exposes data; the published CWE-614 mapping instead names a missing Secure attribute. Exploitation requires low-privileged authentication and user interaction, and the published consequence is limited to confidentiality.
