CVE-2026-56579Network attack vector

License key disclosure via HTTP response

Published Jul 21, 2026 · Updated Jul 21, 2026

Information disclosure in HCL MyCloud 10.8.2 allows remote authenticated users to obtain a license key from an HTTP response. HCL has not identified the affected endpoint or the server-side operation that places the key in the response, so the precise trigger is undisclosed. Reaching the disclosure requires low privileges and high-complexity conditions; the documented consequence is exposure of the license key, not data modification or service interruption.
