Hello,

Thanks for this new version but as far as I can tell, those CVEs also
apply to master and wrynose, can you send the fix for those branches and
ping back here?

Thanks!

Hello,

Same as 1/2, this look like it's needed on master/wrynose. Can you send
the fix there and ping back here?

Thanks!
