# CVE-2026-18622

> 4.7 MEDIUM

## Beschreibung

Foxit PDF Editor/Reader inconsistently alerts users when signature fields are abnormally modified, including alterations to appearance, coordinates, or field duplication. This may mislead users into trusting tampered documents, since the UI cannot accurately reflect the actual integrity status of signatures.
