Description
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.
