The package mathjs before 7.5.1 are vulnerable to Prototype Pollution via the deepExtend function that runs upon configuration updates.
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.
