There was a problem hiding this comment.
Wondering if we could we use rc.getUriInfo().getAbsolutePath() here to verify scheme and authority ?

when the rp sign-in flow completes, OidcRpAuthenticationService redirects the browser to the state value, which OidcRpAuthenticationFilter copies straight from the current request parameters, so a request such as /rp/complete?state=https://evil.example against an authenticated session returns a 303 to an arbitrary external host, an open redirect. the legitimate value is always the application's own request uri, so completeAuthentication now only honours a location that is relative or shares the same scheme and authority as the base path, otherwise it falls back to the configured default location. the added test covers the cross-origin, protocol-relative and userinfo-host variants.
