{"apiVersion":"1.0","identifier":"CVE-2026-68939","description":"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.","publishedAt":"2026-08-18T15:17:00","lastModifiedAt":"2026-08-18T19:17:02","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-68939","cvssScore":2,"cvssVector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00166,"riskScore":0.2,"affectedProduct":"Pyenv","affectedVersions":"<2.8.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-68939","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-68939","en":"https://www.redsauce.net/en/cves/CVE-2026-68939","fr":"https://www.redsauce.net/fr/cves/CVE-2026-68939","pt":"https://www.redsauce.net/pt/cves/CVE-2026-68939","de":"https://www.redsauce.net/de/cves/CVE-2026-68939","sk":"https://www.redsauce.net/sk/cves/CVE-2026-68939","el":"https://www.redsauce.net/el/cves/CVE-2026-68939"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-68939"}}
