CVE-2026-56581 describes a vulnerability in HCLSoftware MyCloud version 10.8.2 where sensitive cookies used in HTTPS sessions do not have the 'Secure' attribute set. This attribute omission means cookies might be sent over unencrypted HTTP connections, potentially exposing session data or authentication tokens to interception. The issue is categorized under CWE-614 (Sensitive Cookie in HTTPS Session Without 'Secure' Attribute). The CVSS 3.1 base score is 2.6, indicating low severity with network attack vector, high attack complexity, low privileges required, and user interaction needed. No vendor advisory or patch is currently available, and no known exploits are reported in the wild.

The vulnerability could allow an attacker to intercept sensitive session cookies if they can induce or observe unencrypted HTTP traffic, potentially leading to unauthorized access to session data or authentication tokens. However, the low CVSS score and requirement for user interaction and high attack complexity limit the practical impact. There is no indication of integrity or availability impact.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should ensure secure deployment practices such as enforcing HTTPS-only access and consider additional compensating controls to protect session cookies. Monitor vendor communications for updates on remediation.
