Oidc Authorizer

A vulnerability was found in lmammino oidc-authorizer up to 0.4.0. Impacted is an unknown function of the file src/handler.rs of the component Lambda Authorizer. The manipulation results in sensitive information in log files. The attack can be executed remotely. `src/handler.rs` logs raw Authorization header values and complete bearer tokens/JWTs on authentication failure paths, potentially exposing credentials through CloudWatch Logs. `src/models.rs` serializes the complete validated JWT claims set with `serde_json::to_string(token_claims).unwrap()` and propagates it through `context["jwtClaims"]` to downstream integrations. This code performs serialization, not deserialization, and does not process attacker-controlled `jwtClaims` input. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
