CVE-2026-68939

Pyenv (Python version manager) prior to 2.8.0 is vulnerable to silent interpreter/version substitution. The is_version_safe() function in libexec/pyenv-version-file-read accepts shell glob metacharacters in .python-version values, and unquoted PYENV_VERSION expansion across multiple libexec scrip...

CVE-2026-68939 Pyenv: Glob/wildcard metacharacters bypass is_version_safe(), causing silent version/interpreter substitution via unquoted expansion (CVE-2022-35861 residual)

Pyenv provides simple Python version management. Prior to 2.8.0, isversionsafe in libexec/pyenv-version-file-read accepts shell glob metacharacters in .python-version values, and unquoted PYENVVERSION expansion in libexec/pyenv-version-name, libexec/pyenv-which, libexec/pyenv-prefix,...
