Another vul similar to https://github.com/component/type/issues/25 is found in component-type. A crafted payload can forge an internal property (nodeType) to manipulate the type detection result.
We found that a maliciously crafted user-input object can type detection result of component-type module. The vulnerability is from the following code: component-type leverages the _isBuffer property from unsafe user-input to detect buffer type information. However, a crafted payload can overwrite this property to manipulate the type detection result. https://github.com/component/type/blob/a581cc14d0b46b8a4c96e2fc99fa76cd7faef5d9/index.js#L39-L46 Reproduce Script
