DEBIAN-CVE-2026-113720

virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, the app-data copy seeder uses shutil.copy to copy cached package files into later environments, causing cached source modes to override the current run's umask. A cache populated under a permissive umask can...

CVE-2026-113719

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-2026-113718

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-2026-113721

virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, ViaTemplateActivator.generate removes an existing output only when Path.exists is true, allowing a dangling symlink to survive and redirect generated activation content, while PyEnvCfg.write opens pyvenv.cfg...

CVE-2026-113717

virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, PipInvoke.getpipinstallcmd handles --seeder pip --download by calling getwheeldownload=False and then allowing pip to consult the configured index, bypassing virtualenv's downloadwheel and verifywheeldigest...

CVE-2026-113723

virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, caller-supplied prompt text can become executable syntax in the bash activation prompt. An attacker must influence the value passed to virtualenv, and a user must subsequently activate the environment and dr...

CVE-2026-113722

virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, virtualenv's ScriptMakerCustom and pip pass an incompletely quoted interpreter path to distlib ScriptMaker when generating POSIX console scripts. When the path contains a space or produces a shebang longer...

DEBIAN-CVE-2026-113716

virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, the builtin creator calls ensuredir for executable, library, and package directories, and ensuredir accepts an existing symlink to a directory because exists follows it. Interpreter creation, seed...

DEBIAN-CVE-2026-113715

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-2026-113720

A flaw was found in virtualenv. When creating new environments, cached package files retain their original permissions rather than respecting the current user file-creation mask umask. On shared systems where an environment directory is accessible to other users, a local attacker can modify these...

CVE-2026-113719

A flaw was found in virtualenv. This vulnerability allows a local attacker to cause arbitrary file deletion outside the target environment directory. When creating an isolated environment in a reused directory, virtualenv processes existing package metadata during cleanup without verifying that...

CVE-2026-113718

A flaw was found in virtualenv. This vulnerability could lead to arbitrary code execution when a user sources a generated xonsh activation script. Under certain multibyte character encodings, improper quoting of non-ASCII directory paths or prompt strings allows quote boundaries to be broken...

CVE-2026-113717

A flaw was found in virtualenv. When creating an environment using the pip seeder with the download option, the tool bypasses its package digest verification routines. A remote attacker controlling a package index could exploit this flaw to provide modified package files without triggering expect...

CVE-2026-113716

A flaw was found in virtualenv. When creating an isolated environment, directory validation resolves existing symbolic links symlinks rather than verifying the intended target destination. A local attacker could exploit this vulnerability by pre-creating a directory tree containing symlinks...

CVE-2026-113715

A flaw was found in virtualenv. When creating virtual environments, the tool fails to properly sanitize destination pathnames containing line-breaking characters before processing configuration files. An attacker who influences the target path can exploit this flaw to inject unauthorized settings...

CVE-2026-113714

A flaw was found in virtualenv. The utility writes downloaded software packages directly into its reusable cache before completing integrity verification checks. An attacker controlling a package repository can exploit this flaw to retain rejected or manipulated packages in the cache, resulting i...

CVE-2026-113713

A flaw was found in virtualenv. When configured to link application data through environment variables or configuration files, virtualenv can leave newly created environments linked to temporary package files that are deleted after setup completes. Because the virtual environment references an...
