Quick assessment

Affected
youlaitech youlai-boot
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

youlai-boot 2.21.1 及之前版本存在一个缺失授权校验的漏洞。该漏洞允许已认证用户通过 PUT /api/v1/roles/{roleId}/menus 接口，为角色分配任意菜单和按钮权限。低权限用户（例如测试用的 GUEST 账户）可将自身角色设为拥有全部权限，并刷新 Redis 中的权限缓存，从而获得等同于管理员的访问权限。
