What it is

The Okta Privileged Access client URL handler does not insert an option terminator before appending the target value to the command-line arguments. When a scaleft:// protocol handler link contains a value beginning with a hyphen, the underlying CLI framework interprets it as a command-line flag, causing unintended modification of the SSH client's behavior.
