For GitLab before 13.0.12, 13.1.6, 13.2.3 after a group transfer occurs, members from a parent group keep their access level on the subgroup leading to improper access.
Weakness
The product does not preserve permissions or incorrectly preserves permissions when copying, restoring, or sharing objects, which can cause them to have less restrictive permissions than intended.
