fast-uri vulnerable to host confusion via literal backslash authority delimiter

Impact fast-uri v4.1.0 and earlier do not treat a literal backslash U+005C as an authority delimiter. Node's native WHATWG URL used by fetch, undici, and Node's http/https clients normalizes \ to / for special schemes http, https, ws, wss, ftp, file, so the two parsers extract different hosts fro...

fast-uri: fast-uri: Path traversal vulnerability allows bypass of security policies

A flaw was found in fast-uri. A remote attacker could exploit this vulnerability by providing a specially crafted Uniform Resource Locator URL containing percent-encoded path separators and dot segments. Due to incorrect processing, fast-uri would decode these elements before proper normalization...
