This issue only affects instances with a webdriver enabled, and `ALLOW_FILE_URI` false or not defined.\n\n### Details\n\nThe check used for URL protocol, `is_safe_url`, allows `file:` as a URL scheme:\n\nhttps://github.com/dgtlmoon/changedetection.io/blob/e0abf0b50507a8a3d0c1d8522ab23519b3e4cdf4/changedetectionio/model/Watch.py#L11-L13\n\nIt later checks if local files are permitted, but one of the preconditions for the check is that the URL starts with `file://`. The issue comes with the fact that the file URI scheme is not required to have double slashes.\n\n> A valid file URI must therefore begin with either `file:/path` (no hostname), `file:///path` (empty hostname), or `file://hostname/path`.\n> — [Wikipedia](https://en.wikipedia.org/wiki/File_URI_scheme#Number_of_slash_characters)\n\nhttps://github.com/dgtlmoon/changedetection.io/blob/e0abf0b50507a8a3d0c1d8522ab23519b3e4cdf4/changedetectionio/processors/__init__.py#L37-L41\n\n### PoC\n\n1.
