Adjust URI host parsing to stop on \ character.
The WHATWG URL parsing algorithm [1] used by browsers says that for "special" URL schemes (which is basically all commonly-used hierarchical schemes, including http, https, ftp, and file), the host portion ends if a \ character is seen, whereas this class previously continued to consider characters part of the hostname. This meant that a malicious URL could be seen as having a "safe" host when viewed by an app but navigate to a different host when passed to a browser.
