CVE-2026-56458Network attack vector

Unauthorized actions and data access via permissive CORS

Published Jul 9, 2026 · Updated Jul 9, 2026

Permissive CORS in HCL DevOps Deploy 8.1 through 8.1.2.6 and 8.2 through 8.2.1.0 allows remote attackers to retrieve sensitive data. The server's CORS policy does not restrict allowed origins to trusted domains, enabling a hostile origin to submit privileged requests and read responses. Exploitation requires user interaction; the documented consequences are unauthorized actions and sensitive-information retrieval, not service interruption.
