CVE-2026-22908Network attack vector

Full system access via unvalidated container images

Published Jan 15, 2026 · Updated Jan 15, 2026

Incorrect privilege assignment in SICK AG TDC-X401GL before 1.4.0 allows remote authenticated users to gain full system access. The container-image upload workflow accepts images without validation, allowing container contents to obtain access beyond the intended isolation boundary; the exact endpoint and omitted validation check are undisclosed. Administrative access to the network interface is required, and successful exploitation exposes system data to reading and modification.
