fast-uri: fast-uri: Host confusion vulnerability via backslash in URI authority

A flaw was found in fast-uri. This vulnerability arises because fast-uri incorrectly parses Uniform Resource Identifiers URIs when a backslash is used in place of a forward slash to introduce the authority component. This discrepancy with Node's native WHATWG URL parser can lead to host confusion...

Interpretation Conflict

Overview fast-uri is a Dependency-free RFC 3986 URI toolbox Affected versions of this package are vulnerable to Interpretation Conflict due to malformed authority introducer handling in parseWithStatus and resolve in index.js. An attacker can bypass host-based URL checks and steer requests to an...
