CVE-2026-63294

Name of the Vulnerable Software and Affected Versions LXD (affected versions not specified)

Description A link following flaw 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 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.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
