Message 350003 - Python tracker

Will the flaw outlined in https://bugs.python.org/issue30458#msg347282 be fixed in python itself? If so, I think a CVE for python should be requested to MITRE (I can request one, in that case).

Moreover, does it make sense to create a new bug to track the new issue? This bug already references 3 CVEs and it would probably just create more confusion to reference a 4th. What do you think?
