Summary

fastest-json-copy vulnerable to Prototype Pollution

Details

fastest-json-copy version 1.0.1 allows an external attacker to edit or add new properties to an object. This is possible because the application does not correctly validate the incoming JSON keys, thus allowing the __proto__ property to be edited.

Severity

5.3 (Medium)
