Overview
Affected versions of this package are vulnerable to Improper Privilege Management in its user rename handling, which reserves the __internal_auditor username as a privileged internal account but does not prevent an ordinary user from renaming their own account to that name. A user with an authenticated account can obtain full tree-path access by renaming themselves to __internal_auditor. This requires an authenticated account able to rename its own user on an affected 2.0.8 or 2.0.9 deployment.
