CVE-2026-22912Network attack vector

Post-login open redirect via unvalidated login parameter

Published Jan 15, 2026 · Updated Jan 15, 2026

Open redirect in SICK AG TDC-X401GL firmware before 1.5.0 allows remote attackers to redirect users to malicious sites after login. The login flow accepts a caller-controlled destination without restricting it to trusted locations and uses that value after authentication. This requires a user to follow a crafted link and authenticate; the redirect supports credential theft but does not modify or interrupt the device.
