Description

Users with the Company admin role (introduced by the company account feature in v4) can assign any role to any user. This also applies to any other user that has the role / assign policy. Any subtree limitation in place does not have any effect.

The role / assign policy is typically only given to administrators, which limits the scope in most cases, but please verify who has this policy in your installaton. The fix ensures that subtree limitations are working as intended.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
