MEDIUM 5.3EPSS 0.64%
Does this matter?
Lower severity and a low EPSS score (0.64%). Track it; it rarely justifies an emergency change on its own.
Description
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.
