CVE-2026-22919Network attack vector

Sensitive-data extraction via unescaped login notice

Published Jan 15, 2026 · Updated Jan 15, 2026

Stored cross-site scripting in SICK AG TDC-X401GL firmware before 1.5.0 allows remote authenticated users to extract sensitive data. The Control Center renders an administrator-configured system-use notification on the pre-authentication login page without neutralizing malicious content. Administrative access is required to store the payload; visitors to the login page can encounter the injected content, with reported effects limited to data disclosure and page integrity.
