Summary
It was discovered that the Python ipaddress module contained incorrect
information about which IP address ranges were considered “private” or
“globally reachable”. This could possibly result in applications applying
incorrect security policies. This issue only affected Ubuntu 14.04 LTS
and Ubuntu 16.04 LTS. (CVE-2024-4032)
It was discovered that Python incorrectly handled quoting path names when
using the venv module. A local attacker able to control virtual
environments could possibly use this issue to execute arbitrary code when
the virtual environment is activated. (CVE-2024-9287)
It was discovered that Python incorrectly handled parsing bracketed hosts.
A remote attacker could possibly use this issue to perform a Server-Side
Request Forgery (SSRF) attack. This issue only affected Ubuntu 14.04 LTS
and Ubuntu 16.04 LTS. (CVE-2024-11168)
It was discovered that Python incorrectly handled parsing domain names that
included square brackets. A remote attacker could possibly use this issue
to perform a Server-Side Request Forgery (SSRF) attack. (CVE-2025-0938)

High 7.5
Incorrect IPv4 and IPv6 private ranges
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.IPv4Networ…

Medium 6.3
Improper validation of IPv6 and IPvFuture addresses
The urllib.parse.urlsplit() and urlparse() functions improperly validated bracketed hosts (`[]`), allowing hosts that weren't IPv6 or IPvFuture. This behavior was not conformant to RFC 3986 and potentially enabled SSRF if a URL is processed by more than one U…

Medium 6.3
URL parser allowed square brackets in domain names
The Python standard library functions `urllib.parse.urlsplit` and `urlparse` accepted domain names that included square brackets which isn't valid according to RFC 3986. Square brackets are only meant to be used as delimiters for specifying IPv6 and IPvFuture…

Virtual environment (venv) activation scripts don't quote paths
A vulnerability has been found in the CPython `venv` module and CLI where path names provided when creating a virtual environment were not quoted properly, allowing the creator to inject commands into virtual environment "activation" scripts (ie "source venv/…
