CVE-2026-113724

A flaw was found in virtualenv. When cleaning up files, the deletion error-handling routine follows symbolic links when attempting to restore write permissions for removal. A local attacker can exploit this issue by planting a symbolic link pointing to a file owned by the executing user, causing...

CVE-2026-113721

A flaw was found in virtualenv. A local attacker can exploit this issue by pre-creating symbolic or hard links in a destination directory before an environment is set up. Because virtualenv does not properly check or replace existing links when writing configuration and activation files, it can...

CVE-2026-113867

Thunderbird did not escape attribute values when serializing outgoing XMPP stanzas. Because values from incoming requests were echoed back in automatic replies, a remote XMPP user could send a crafted request that caused Thunderbird to inject arbitrary stanzas into the user's connection, which th...

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...

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-2026-113713

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...

CVE-2026-31431 / GHSA-2274-3hgr-wxv6 — algifaead Remediator Severity: High CVSS 7.8 — CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H Background CVE-2026-31431 is a local privilege escalation vulnerability in the Linux kernel's algifaead module AFALG AEAD crypto socket interface. A low-privileged...

Symlink Attack

Overview Affected versions of this package are vulnerable to Symlink Attack via the onerror handler in src/virtualenv/util/path/sync.py, which previously called os.chmod on a path without first checking whether it is a symbolic link. On Windows, when a read-only file cannot be deleted during a tr...

Symlink Attack

Overview Affected versions of this package are vulnerable to Symlink Attack via ViaTemplateActivator.generate in src/virtualenv/activation/viatemplate.py, which checks whether a destination file exists with Path.exists before unlinking it and writing new content. A local attacker who can race the...

CVE-2026-113720

The virtualenv tool (prior to version 21.14.9 ) contains a vulnerability where the app-data copy seeder uses shutil.copy() to move cached package files into new environments. This causes files to retain source modes from a previous cache, potentially overriding the current run's umask . If the ca...

CVE-2026-113720 virtualenv: Seeded files retain permissions from an older cache

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-2026-80353

A flaw was found in Apache Tomcat. A local attacker can gain unauthorized access to Unix domain communication sockets due to a time-of-check to time-of-use TOCTOU race condition in the APR/Native connector. When the connector initializes a socket, a brief timing window exists before restrictive...

CVE-2026-111925

A flaw was found in Mopidy. A remote, unauthenticated attacker can access local files outside the configured media directories due to missing path containment checks in the file library component. By sending requests with manipulated file paths over network interfaces, an attacker can determine...

CVE-2026-113716

The virtualenv tool, prior to version 21.14.9 , is vulnerable to a symlink following issue during builtin environment creation. The ensure_dir() function improperly follows existing symlinks for executable, library, and package directories. If a local attacker prepares a tree containing a symlink...

CVE-2026-113867 Stanza injection in XMPP chat

Thunderbird did not escape attribute values when serializing outgoing XMPP stanzas. Because values from incoming requests were echoed back in automatic replies, a remote XMPP user could send a crafted request that caused Thunderbird to inject arbitrary stanzas into the user's connection, which th...
