    Summary: User authorization bug leading to privilege escalation in warpgate

    Details: Warpgate is an open source SSH, HTTPS and MySQL bastion host for Linux. In affected versions there is a privilege escalation vulnerability through a non-admin user's account.

All installations prior to version 0.9.0 are affected. All users are advised to upgrade. There are no known workarounds for this vulnerability.
