org.webjars.npm:fast-uri@3.1.5

org.webjars.npm:fast-uri is a Dependency-free RFC 3986 URI toolbox

Affected versions of this package are vulnerable to Improper Encoding or Escaping of Output that enables authority injection in the recomposeAuthority function, which escapes the userinfo and host components but concatenates the port field verbatim, so non-digit characters in the port introduce authority delimiters. An attacker can restructure the URI to redirect requests to a server they control by supplying a port value such as @127.0.0.1:8124, which demotes the legitimate host to userinfo and yields http://trusted.example:@127.0.0.1:8124/app. This requires the application to build URIs from separate components and assign untrusted data directly to the port field of an object passed to serialize(), normalize(), or equal(), and ports obtained via parse() are unaffected because parsing validates digit-only values.

A fix was pushed into the master branch but not yet published.
