CVE-2021-22027Known exploitationNetwork attack vector

Information disclosure via unrestricted server requests

Published Aug 30, 2021 · Updated Aug 3, 2024

Server-Side Request Forgery in VMware vRealize Operations Manager 8.x before 8.5 allows remote attackers to disclose information. The API endpoint accepts attacker-controlled destinations and makes server-side requests without restricting internal targets. Network access to the API is sufficient and no authentication is required; the documented consequence is information disclosure rather than integrity or availability impact.
