Description

JumpServer is an open source bastion host and an operation and maintenance security audit system. Prior to 4.10.17, a user with the users.invite_user permission can submit an existing member to POST /api/v1/users/users/invite/, causing the organization invitation logic in apps/users/api/user.py to execute user.org_roles.set(org_roles) and replace the member's existing organization roles, which can escalate privileges or downgrade administrators. This issue is fixed in version 4.10.17.
