CVE-2023-38494Public exploitNetwork attack vector

Authenticated cross-tenant disclosure via missing controller authorization

Published Aug 4, 2023 · Updated Oct 8, 2024

Missing authorization in MeterSphere Cloud before 2.10.4 LTS allows remote authenticated users to read other teams' member data. GroupController and BaseUserController accept attacker-selected user, team, or project identifiers and return group or member records without verifying membership or read permission. A basic authenticated account can expose other tenants' email addresses, names, phone numbers, workspace identifiers, and integration identifiers.
