## Summary

The NoviGest Desktop App from Tactis is affected by a flaw in its SAFT file import feature that lets a malicious XML file cause the app to read local files it can access. If the app runs with elevated privileges, an attacker could expose sensitive system files.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Tactis NoviGest Desktop App: NoviGest Desktop App prior to version 8.0.0-300

## Description

XML External Entity (XXE) injection vulnerability in the SAFT import feature of the NoviGest Desktop App. The application processes user-controlled XML files using a JAXB Unmarshaller without properly disabling external entity resolution. An attacker with access to this functionality could provide a manipulated XML file to read local files accessible to the application process. If the application runs with elevated privileges, sensitive system files could be exposed.
