This affects the package open-graph before 0.2.6. The function parse could be tricked into adding or modifying properties of Object.prototype using a proto or constructor payload.

Weakness

The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.

Open-graph Open-graph_project * 0.2.6 (excluding)
