### Summary When a WebDriver is used to fetch files source:file:///etc/passwd can be used to retrieve local system files, where the more traditional file:///etc/passwd gets blocked

### Details The root cause is the payload source:file:///etc/passwdpasses the regex [here](https://github.com/dgtlmoon/changedetection.io/blob/master/changedetectionio/model/Watch.py#L19) and also passes the check [here](https://github.com/dgtlmoon/changedetection.io/blob/master/changedetectionio/processors/__init__.py#L35) where a traditional file:///etc/passwd would get blocked
