autoar-extractor.c in GNOME gnome-autoar before 0.3.1, as used by GNOME Shell, Nautilus, and other software, allows Directory Traversal during extraction because it lacks a check of whether a file's parent is a symlink in certain complex situations. NOTE: this issue exists because of an incomplete fix for CVE-2020-36241.

This affects the package juce-framework/JUCE before 6.1.5. This vulnerability is triggered when a malicious archive is crafted with an entry containing a symbolic link. When extracted, the symbolic link is followed outside of the target dir allowing writing arbitrary files on the target host. In some cases, this can allow an attacker to execute arbitrary code. The vulnerable code is in the ZipFile::uncompressEntry function in juce_ZipFile.cpp and is executed when the archive is extracted upon calling uncompressTo() on a ZipFile object.

Yubico pam-u2f 1.0.7 attempts parsing of the configured authfile (default $HOME/.config/Yubico/u2f_keys) as root (unless openasuser was enabled), and does not properly verify that the path lacks symlinks pointing to other files on the system owned by root. If the debug option is enabled in the PAM configuration, part of the file contents of a symlink target will be logged, possibly revealing sensitive information.

Directory traversal vulnerability in the WordPress Download Manager plugin for WordPress allows remote attackers to read arbitrary files via a .. (dot dot) in the fname parameter to (1) views/file_download.php or (2) file_download.php.

This issue was addressed with improved validation of symlinks. This issue is fixed in tvOS 26.1, watchOS 26.1, macOS Tahoe 26.1, iOS 26.1 and iPadOS 26.1, macOS Sequoia 15.7.2, macOS Sonoma 14.8.2, visionOS 26.1. An app may be able to access protected user data.

Information leakage vulnerability in the administrative console in Dialogic PowerMedia XMS through 3.5 allows remote attackers to read arbitrary files from the /var/ directory because a symlink exists under the web root.

Improper link resolution before file access ('link following') in Windows Installer allows an authorized attacker to disclose information locally.

Backup in Apple iOS before 8.4.1 allows attackers to bypass intended restrictions on filesystem access via a crafted app that creates a symlink.

This issue was addressed with improved handling of symlinks. This issue is fixed in macOS Sequoia 15.1. An app may be able to access sensitive user data.
