When using URIBuilder's constructor with a malformed url argument, host passed in by setHost call not honored.
String path = "@notexample.com/mypath"
URI uri = new URIBuilder(path).setHost("example.com").build();
This is caused by the original string being passed into the constructor being treated as the path, but not verifying the presence of a leading / character.
This can be seen with other arguments:
path = "example" -> //example.comexample
Fix: URIBuilder should ensure path starts with a leading /.
Reason priority is considered Major:
In our case, this caused a security vulnerability which was discovered by researcher James Kettle (@albinowax on twitter). The user-provided path was able to override our specified host, resulting in giving network access to a sensitive environment. We worked around this in our code by ensuring the leading /, but this seems like something better handled by the framework.
PS. If you agree this should be fixed, I'm happy to submit a pull request.
