CVE Published:

Summary

The “ipaddress” module contained incorrect information about whether certain IPv4 and IPv6 addresses were designated as “globally reachable” or “private”. This affected the is_private and is_global properties of the ipaddress.IPv4Address, ipaddress.IPv4Network, ipaddress.IPv6Address, and ipaddress.IPv6Network classes, where values wouldn’t be returned in accordance with the latest information from the IANA Special-Purpose Address Registries.

CPython 3.12.4 and 3.13.0a6 contain updated information from these registries and thus have the intended behavior.

Affected Version(s)

CPython 0 < 3.12.4

CPython 3.13.0a1 < 3.13.0a6
