Release Notes

protocolbuffers/protobuf-go (google.golang.org/protobuf)

v1.33.0

Compare Source

This release contains one security fix:

  • encoding/protojson: Unmarshal could enter an infinite loop when unmarshaling certain forms of invalid JSON. This condition can occur when unmarshaling into a message which contains a google.protobuf.Any value, or when the UnmarshalOptions.DiscardUnknown option is set. Unmarshal now correctly returns an error when handling these inputs. This is CVE-2024-24786.
