CVE-2026-1386

A UNIX symbolic link following issue in the jailer component in Firecracker version  v1.13.1 and earlier and 1.14.0 on Linux may allow a local host user with write access to the pre-created jailer directories to overwrite arbitrary host files via a symlink attack during the initialization copy at jailer startup, if the jailer is executed with root privileges. 

To mitigate this issue, users should upgrade to version v1.13.2 or 1.14.1 or above.
