The project summary here: https://bugs.mojang.com/projects/MC/summary
Has a link to create bug reports "Report a New Bug", and it opens
&security=10317
But this security level gives an error, even if you try to select a value from the selectbox:
The security level is invalid.
I can confirm that this is an issue. Previously, 10317 was used as the "Minecraft - Public" security level, but this no longer exists, so the value should either be removed, or changed to -1.
