Incus is a system container and virtual machine manager. Prior to version 7.3.0, a malicious image containing a "metadata.yaml" symlink pointing to an arbitrary host path allows an authenticated Incus user to read or overwrite any file on the host as root via the instance metadata API. The "exec-output" and "templates/" paths were patched in a prior release using "Lstat" rejection and "os.OpenRoot" confinement; "metadata.yaml" was not included in either patch and remains exploitable. Version 7.3.0 patches the issue.
