Vulnerability details
The vulnerability allows a remote user to escalate privileges.
The vulnerability exists due to improper authorization in the default team creation API endpoints when creating or reusing a project, customer, or activity team whose name matches an existing team. A remote user can create or use a project whose name matches an existing team to escalate privileges.
Exploitation requires project permission-management privileges, and the issue occurs because an existing team is reused and the current user is added as a teamlead without authorization checks.
