Hi,

The following vulnerability was published for pyenv.

CVE-2026-68939[0]:
| Pyenv provides simple Python version management. Prior to 2.8.0,
| is_version_safe() in libexec/pyenv-version-file-read accepts shell
| glob metacharacters in .python-version values, and unquoted
| PYENV_VERSION expansion in libexec/pyenv-version-name,
| libexec/pyenv-which, libexec/pyenv-prefix, libexec/pyenv-local,
| libexec/pyenv-global, libexec/pyenv-version, and libexec/pyenv-
| versions pathname-expands the value against the current directory,
| allowing a matching attacker-controlled file to silently select a
| different installed interpreter or version. This issue is fixed in
| version 2.8.0.
