CVE-2026-12084Network attack vector

Data retrieval and privileged actions via permissive CORS

Published Jun 30, 2026 · Updated Jun 30, 2026

CORS misconfiguration in IBM DevOps Deploy 8.1 through 8.1.2.6 and 8.2 through 8.2.1.0 allows remote attackers to retrieve data. The server's CORS policy accepts origins beyond trusted domains, exposing authenticated responses and privileged actions to untrusted web content. Exploitation requires user interaction while a valid Deploy session is available; consequences are limited to sensitive-information retrieval and actions permitted by that user's session.
