Arbitrary Code Execution in json-ptr
Quick fix
GHSA-x5r6-x823-9848 — json-ptr: upgrade to the fixed version with the command below.
npm install json-ptr@2.1.0Details
npm `json-ptr` before 2.1.0 has an arbitrary code execution vulnerability. The issue occurs in the [set operation](https://flitbit.github.io/json-ptr/classes/_src_pointer_.jsonpointer.htmlset) when the force flag is set to true. The function recursively set the property in the target object, however it does not properly check the key being set, leading to a prototype pollution.
