Overview

Affected versions of this package are vulnerable to Improper Check for Dropped Privileges due to the omission of constraint extensions such as restrict-destination-v00@openssh.com when adding a key to a remote agent. An attacker can bypass intended key usage restrictions by forwarding keys without the associated constraints, enabling unrestricted use of the key on the remote host.
