{"id":"GHSA-x5r6-x823-9848","summary":"Arbitrary Code Execution in json-ptr","details":"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.
