CVE-2024-4032
HIGH7.5EPSS 1.1%Incorrect IPv4 and IPv6 private ranges
Published: 6/17/2024Modified: 5/11/2026
Description
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 3.13.0 contain updated information from these registries and thus have the intended behavior.
