## Overview

CVRF-CSAF-Converter before 1.0.0-rc2 resolves XML External Entities (XXE). This leads to the inclusion of arbitrary (local) file content into the generated output document. An attacker can exploit this to disclose information from the system running the converter.

## Affected packages

- `cvrf2csaf < 1.0.0rc2`

## Remediation

Upgrade to a patched release:

- `cvrf2csaf 1.0.0rc2`
