Overview

Affected versions of this package are vulnerable to Improper Privilege Management in the createUser process in auth/proxy.go when proxy authentication is enabled and default settings include non-empty commands. An attacker can gain unauthorized execution capabilities and access to restricted commands by triggering automatic user provisioning through a crafted proxy-authenticated login. This is only exploitable if proxy authentication is enabled, execution is not disabled, and the administrator has configured default commands.
