CVE-2024-48932Public exploitNetwork attack vector

Username disclosure via unauthorized user-name API

Published Oct 24, 2024 · Updated Nov 5, 2025

Missing authorization in the ZimaOS user-name API before 1.5.0 allows remote attackers to enumerate account usernames over the network. The /v1/users/name endpoint returns its username data without requiring an authentication or authorization token. A network-reachable instance is sufficient; disclosure is limited to usernames, which can enable password guessing or targeted phishing.
