CVE-2021-22026Network attack vector

Information disclosure via undisclosed API endpoint SSRF

Published Aug 30, 2021 · Updated Aug 3, 2024

SSRF in the VMware vRealize Operations Manager API before 8.5 allows remote attackers to disclose information through crafted requests. VMware identifies multiple affected API endpoints but has not disclosed the endpoint paths or the URL-validation error that permits attacker-controlled outbound requests. Network access to the API is sufficient and authentication or user interaction is not required; the documented consequence is information disclosure.
