= Changes in redirect URI verification when using wildcards

Because of security concerns, the redirect URI verification now performs a exact string matching (no wildcard involved) if the passed redirect uri contains a `userinfo` part or its `path` accesses parent directory (`/../`).

The full wildcard `*` can still be used as a valid redirect in development for http(s) URIs with those characteristics. In production environments a exact valid redirect URI without wildcard needs to be configured for any URI of that type.

Please note that wildcard valid redirect URIs are not recommended for production and not covered by the OAuth 2.0 specification.

= Changes to the `org.keycloak.userprofile.UserProfileDecorator` interface

To properly support multiple user storage providers within a realm, the `org.keycloak.userprofile.UserProfileDecorator`
interface has changed.

The `decorateUserProfile` method is no longer invoked when parsing the user profile configuration for the first time (and caching it),
but everytime a user is being managed through the user profile provider. As a result, the method changed its contract to:

```java
List<AttributeMetadata> decorateUserProfile(String providerId, UserProfileMetadata metadata)
```

Differently than the previous contract and behavior, this method is only invoked for the user storage provider from where the user
was loaded from.
