CVSSv4: 9.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary code.
The vulnerability exists due to download of code without integrity check in the download_wheel() function when downloading pip or setuptools seed wheels. A remote attacker can substitute a wheel served under the same distribution, version, and filename to execute arbitrary code.
The issue affects wheels retrieved through the periodic-update feature or the --download flag.

The vulnerability allows a local user to inject configuration values.
The vulnerability exists due to improper neutralization of line boundaries in PyEnvCfg.write() when serializing prompt values into pyvenv.cfg. A local user can supply a crafted prompt containing line boundaries to inject configuration values.
Exploitation requires the prompt to be derived from externally influenced data.
