CVE-2022-35861: Pyenv

High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days.

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.)

Affected products

• Pyenv Pyenv: from 1.2.24, up to and including 2.3.2
