CVE-2026-63343: CWE-73: External Control of File Name or Path in lxc incusCVE-2026-63343 0 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. Join the discussion | CVE Database V5 | 08/21/2026, 14:53:26 UTC Added: 08/21/2026, 15:08:24 UTC |
