<details>
<summary>grpc/grpc-go (google.golang.org/grpc)</summary>

### [`v1.81.1`](https://redirect.github.com/grpc/grpc-go/releases/tag/v1.81.1): Release 1.81.1

[Compare Source](https://redirect.github.com/grpc/grpc-go/compare/v1.81.0...v1.81.1)

### Security

- xds/rbac: Fix a potential authorization bypass caused by incorrectly falling through URI/DNS SANs to Subject Distinguished Name (DN) when matching the authenticated principal name. With this fix, only the first non-empty identity source will be used, as per [gRFC A41](https://redirect.github.com/grpc/proposal/blob/master/A41-xds-rbac.md). ([#&#8203;9111](https://redirect.github.com/grpc/grpc-go/issues/9111))
  - Special Thanks: [@&#8203;al4an444](https://redirect.github.com/al4an444)

### Bug Fixes

- otel: Segregate client and server RPC information used for metrics and traces, to avoid one overwriting the other. ([#&#8203;9081](https://redirect.github.com/grpc/grpc-go/issues/9081))
