Affected: Homebrew: cobo-cli

### Impact

`Schema.load(data, many=True)` is vulnerable to denial of service attacks. A moderately sized request can consume a disproportionate amount of CPU time.

### Patches

4.1.2, 3.26.2

### Workarounds

```py # Fail fast def load_many(schema, data, **kwargs): if not isinstance(data, list): raise ValidationError(['Invalid input type.']) return [schema.load(item, **kwargs) for item in data] ```
