Does this impact Stalwart mail server in any way? If yes, is there a timeline for a fix? (I know the disclosure of this was apparently handled very badly and the holidays are coming up)

This was discussed on Discord. Whether this vulnerability affects Stalwart is going to be tested after v0.5.0 is released next week. If a vulnerability is found a patch will be released immediately.
