CVE-2026-113715 virtualenv: Venv configuration readback can reinterpret path boundaries

virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, the stdlib venv creator reads generated pyvenv.cfg with str.splitlines and merges parsed keys over virtualenv's selected configuration. An untrusted caller who influences the destination pathname can include...

CVE-2026-113719 virtualenv: Seed replacement does not contain metadata deletion paths

virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, PipInstall.uninstallpreviousversion accepts existing seed-package metadata and uninstalldist joins entries from toplevel.txt and RECORD to site-packages without checking containment. When a reused destinatio...

CVE-2026-113719

The virtualenv tool is vulnerable to a path traversal issue prior to version 21.14.9 . The PipInstall._uninstall_previous_version() function accepts existing seed-package metadata, and _uninstall_dist() joins entries from top_level.txt and RECORD without verifying directory containment. If a reus...

CVE-2026-113718 virtualenv: Xonsh activation literals depend on the script decoding codec

virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, POSIX xonsh activation quote uses repr to write printable non-ASCII prompt or destination data into UTF-8 activate.xsh, while xonsh can read that script using $XONSHENCODING. Under a legacy multibyte codec...

CVE-2026-113718

The virtualenv tool is vulnerable to code injection in versions prior to 21.14.9 . The issue exists in the POSIX xonsh activation quote() function, which uses repr() to write non-ASCII data into the UTF-8 activate.xsh script. When using legacy multibyte codecs like GBK or Big5 , a UTF-8 trail byt...

Arbitrary Code Injection

Overview Affected versions of this package are vulnerable to Arbitrary Code Injection via the quote method in src/virtualenv/activation/xonsh/init.py, which uses repr to encode string literals written into the xonsh activation script. Because repr does not guarantee ASCII-safe output, non-ASCII...
