## Affected

- pig-mesh pig: through 4.1.1

## Description

pig through 4.1.1 contains a missing authorization vulnerability in SysUserController.user that allows any authenticated user to read other users' profiles via GET /admin/user/details/{id}. Low-privilege attackers can enumerate sequential user ids to obtain usernames, real names, phone numbers, emails, linked third-party accounts, and role assignments.
