Privilege Escalation via .python-version File in pyenv

CVE-2022-35861 · HIGH Severity

CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

pyenv 1.2.24 through 2.3.2 allows local users to gain privileges via a .python-version file in the current working directory. An attacker can craft a Python version string in .python-version to execute shims under their control. (Shims are executables that pass a command along to a specific version of pyenv. The version string is used to construct the path to the command, and there is no validation of whether the version specified is a valid version. Thus, relative path traversal can occur.)
