Improper Check for Unusual or Exceptional Conditions Affecting protobufjs-cli package, versions <1.3.3>=2.0.0 <2.5.1

protobufjs-cli is a Translates between file formats and generates static code as well as TypeScript definitions.

Affected versions of this package are vulnerable to Improper Check for Unusual or Exceptional Conditions in the schema-derived names that collide with runtime-significant properties. An attacker can cause affected message or service types to become unusable, resulting in denial of service for the relevant processing path, by providing or influencing protobuf schemas or JSON descriptors containing problematic names such as hasOwnProperty, $type, or rpcCall.

This vulnerability can be mitigated by not loading protobuf schemas or JSON descriptors from untrusted sources, or by validating and rejecting schema-derived field, oneof, and service method names that match the problematic names before loading.
