Description
Nezha from 1.7.0 before 2.3.15 contains an information disclosure vulnerability that allows authenticated members to enumerate other tenants' server IDs through differential responses. Attackers can sweep sequential IDs against getServerConfig and setServerConfig, distinguishing 'permission denied' from success payloads to map other users' servers.
