Technical details

Two missing object-level authorization checks in the API: (1) ProjectMemberViewSet.partial_update nests all authorization logic inside a role-update branch, allowing an attacker to omit the role field and modify the is_active flag of any other member via PATCH, including deactivating project admins; (2) ProjectMemberPreferenceEndpoint.patch trusts the member_id path parameter and permits overwriting any member's preferences. Both flaws require only guest project membership and allow privilege escalation or membership disruption.
