Title
Authorizer before 2.4.2 Password Reset Poisoning via x-authorizer-url gRPC metadata
Summary
Authorizer before 2.4.2 contains a password reset poisoning vulnerability that allows unauthenticated attackers to control emailed link hosts by supplying x-authorizer-url gRPC metadata. Attackers can send this metadata to the gRPC port or a Grpc-Metadata-X-Authorizer-Url header through the REST gateway to capture reset or magic-link tokens and take over accounts.

Title
Authorizer: Unvalidated redirect_uri in /authorize leaks OAuth2 tokens to attacker-controlled URL
Summary
Authorizer is an open-source, self-hostable authentication and authorization server. Prior to version 2.2.1, the `/authorize` endpoint accepts any `redirect_uri` without validating it against `AllowedOrigins`. When `response_type=token` or `response_type=id_token`, the server appends `access_token`, `id_token`, and `refresh_token` as query parameters and issues a 302 redirect to the attacker-supplied URL. An unauthenticated attacker can obtain the required `client_id` from the public `/graphql?query={meta{client_id}}` endpoint. A partial fix was applied in v2.0.1 to other handlers (`oauth_login`, `verify_email`, `magic_link_login`, `forgot_password`, `invite_members`, `oauth_callback`) but `/authorize` was not included. Version 2.2.1 contains a more complete fix.
