CVE-2022-3895

Cross-site scripting via unsanitized interface output

Published Nov 15, 2022 · Updated Apr 29, 2025

Cross-site scripting in Hallo Welt! GmbH Common User Interface Component 3.0.0 through 3.0.4 allows attackers to inject arbitrary HTML. Some interface elements place output into rendered pages without proper sanitization; the vendor has not disclosed the affected elements or input path. Published assessments disagree on reachability: the vendor treats the path as local and unauthenticated, while NVD treats it as network-based with user interaction; impact is confined to browser-side data exposure or modification.
