This commit addresses a critical security vulnerability where low-privileged
users (members) could invite high-privileged users (admins/owners) to teams,
allowing them to escalate their own privileges through password reset.
Root Causes Fixed:
1. TeamPolicy authorization checks were commented out, allowing all team
members to manage invitations instead of just admins/owners
2. Missing role elevation checks in InviteLink component allowed members
to invite users with higher privileges
Security Fixes:
1. app/Policies/TeamPolicy.php
- Uncommented and enforced authorization checks for:
* update() - Only admins/owners can update team settings
* delete() - Only admins/owners can delete teams
* manageMembers() - Only admins/owners can manage team members
* viewAdmin() - Only admins/owners can view admin panel
* manageInvitations() - Only admins/owners can manage invitations
2. app/Livewire/Team/InviteLink.php
- Added explicit role elevation checks to prevent:
* Members from inviting admins or owners
* Admins from inviting owners (defense-in-depth)
- Validates that inviter has sufficient privileges for target role
Test Coverage:
1. tests/Feature/TeamPolicyTest.php
- 24 comprehensive tests covering all policy methods
- Tests for owner, admin, member, and non-member access
- Specific tests for the privilege escalation vulnerability
2. tests/Feature/TeamInvitationPrivilegeEscalationTest.php
- 11 tests covering all role elevation scenarios
- Tests member → admin/owner escalation (blocked)
- Tests admin → owner escalation (blocked)
- Tests valid invitation paths for each role
Impact:
- Prevents privilege escalation attacks
- Protects all Coolify instances from unauthorized access
- Enforces proper role hierarchy in team management
