CVE-2026-21761Network attack vector

Authenticated resource access via permissive cross-origin policy

Published Jul 17, 2026 · Updated Jul 17, 2026

CORS misconfiguration in HCLSoftware DevOps Loop 2.0.0 allows remote authenticated users to access application resources cross-origin. An undisclosed endpoint permits untrusted origins, but HCLSoftware has not identified the endpoint or disclosed its policy logic. Low-privileged access is required; successful requests can read or alter application resources, while availability is unaffected.
