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.
Conclusion & alert: CVE-2024-4032 is rated Moderate Risk (50.7/100): CVSS High severity, with medium exploitation likelihood (EPSS 1.04%). Mandatory action: Review affected assets and schedule remediation.
