If it is critical please submit it.

Please report vulnerabilties through Github Advisories.

Don't be afraid to report a vulnerability! If we have to close it there are no consequences!

If a vulnerability is of high severity it will be looked into reasonably fast. Vulnerabilties get accepted and denied all the time, if your vulnerability is denied and you believe it was denied falsely than you can either reopen it or create a new one if it is of high priority.
