This vulnerability is located in the transitive dependency `golang.org/x/net v0.19.0`, [CVE-2023-45288](https://www.cve.org/CVERecord?id=CVE-2023-45288)\n\n### Patches\n3.0.0-next versions are fixed on >= [3.0.0-next.3](https://github.com/zitadel/zitadel-go/releases/tag/v3.0.0-next.3)\n\nZITADEL recommends upgrading to the latest versions available in due course.\n\n### Workarounds\n\nIf updating the zitadel-go library is not an option, updating the affected (transient) dependencies works as a workaround.\n\n### Details\n\n#### Direct deps:\n\n- [GO-2024-2631](https://pkg.go.dev/vuln/GO-2024-2631) Decompression bomb vulnerability in github.com/go-jose/go-jose\n  - github.com/go-jose/go-jose/v3 Fixed in v3.0.3.\n\nThis module is necessary because [github.com/go-jose/go-jose/v3](https://pkg.go.dev/github.com/go-jose/go-jose/v3@v3.0.1) is imported in `github.com/zitadel/zitadel-go/v3/pkg/client/system`.\n\n- [GO-2024-2611](https://pkg.go.dev/vuln/GO-2024-2611) Infinite loop in JSON unmarshaling in google.golang.org/protobuf\n  - google.golang.org/protobuf/encoding/protojson\n  - google.golang.org/protobuf/internal/encoding/json Fixed in v1.33.0.\n\nThis module is necessary because [google.golang.org/protobuf/reflect/protoreflect](https://pkg.go.dev/google.golang.org/protobuf@v1.31.0/reflect/protoreflect) is imported in `github.com/zitadel/zitadel-go/v3/example/api/grpc/proto`.\n\n#### Transitive deps:\n- [GO-2024-2687](https://pkg.go.dev/vuln/GO-2024-2687) HTTP/2 CONTINUATION flood in net/http\n  - golang.org/x/net/http2 Fixed in v0.23.0.\n\nThis module is necessary because [golang.org/x/net/trace](https://pkg.go.dev/golang.org/x/net@v0.19.0/trace) is imported in:\n  - `github.com/zitadel/zitadel-go/v3/example/api/grpc`\n  -
