CWE-59: Link Following vulnerabilities

A link following vulnerability in LXD allows an attacker to achieve arbitrary file read and write operations on the host system. When importing or unpacking an image archive, LXD fails to validate whether the metadata.yaml file is a symbolic link. An attacker can exploit this flaw by providing a crafted image archive with a symlinked metadata.yaml file pointing to target file paths on the host system.

A link following vulnerability in LXD allows an attacker to achieve root command execution on the host system. During the import or unpacking of crafted image or backup archives, LXD fails to properly validate and confine the backup.yaml file when it exists as a symbolic link. An attacker can exploit this flaw by providing a malicious archive with a symlinked backup.yaml file, causing LXD to process unconfined configuration metadata and execute arbitrary commands with root privileges.

CVE-2026-17106, known as CopyEscape, is a high-severity vulnerability in Docker's 'docker cp' command that allows a malicious container to write arbitrary files to the host filesystem. The flaw stems from a filesystem race condition during archive creation combined with unsafe symbolic link handling during extraction. This can lead to arbitrary file creation or overwriting on the host and potentially code execution depending on the privileges of the Docker CLI user. Docker has released official fixes in Docker Engine/CLI version 29.7.2 and later, Docker Desktop 4.86.0 and later, and Docker Sandboxes 0.38.0 and later.

The affected TP-Link Aginet devices do not properly validate symbolic links created on external USB storage devices. By placing a crafted symbolic link on supported storage media, an attacker may cause the system to resolve the link. Successful exploitation may allow unauthorized read access to sensitive files within the device filesystem.

Local unprivileged users can terminate arbitrary local processes via a systemd-oomd IPC API due to a missing path traversal validation.

File::Rotate::Simple versions before 0.4.0 for Perl create the target of dangling symlinks when rotating files. When the file to be rotated is a symbolic link to a missing file, and the touch option is enabled, then the rotate method assumes that the file is absent (since the existence check is against the target), and does not rotate it. But it touches the file, which creates the target. An attacker that has the ability to create the symlink can use this to create an arbitrary file with permissions of the process rotating the files (which may be different from the process that normally writes to the log file that is being rotated). Note that the touch option is disabled by default.

Nx versions from 20.8.0 up to but not including 22.7.7 and 23.0.2 have a path traversal vulnerability in the self-hosted HTTP remote cache feature. This flaw allows a malicious or man-in-the-middle remote cache server to craft tar archives that write files outside the intended cache directory, potentially leading to remote code execution. The default local cache and Nx Cloud are not affected. The issue is fixed in versions 22.7.7 and 23.0.2.

Link following vulnerability in the Uninstaller component in CCleaner prior to 7.10.1464 on Windows allows a local, low-privileged attacker to escalate privileges to SYSTEM via a symlink/junction created during application uninstallation, which CCleaner follows when deleting the application's data folder with elevated integrity.

Dell Monitor driver, version 1.0.0.0, contains an Improper Link Resolution Before File Access ('Link Following') vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of Privileges.

Kenwood DNR1007XR Firmware Update Link Following Code Execution Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Kenwood DNR1007XR devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the firmware update process. By creating a symbolic link, an attacker can abuse the service to move a file to an arbitrary location. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-28751.
