> Hi, 
> We have plain text injection problem with mina 2.0.4 (It is reproducible with 2.0.9 as
> This is the problem
> The FTP client sends the commands:
> auth tls\r\nfeat
> and the feat command is executed.
> It became obvious, that the output was received encrypted. However, the command was sent
unencrypted. In general, it is possible to inject commands in plain-text during the initialization
of the encrypted 
> channel. This can be abused for attacks against the user.
> All unencrypted commands that are send after “auth tls” must be ignored.
> Do you plan to fix this issue ?
