    Regular Expression Denial of Service



    Affected versions of parsejson are vulnerable to a regular expression denial of service when parsing untrusted user input.


    The parsejson package has not been functionally updated since it was initially released.

    Additionally, it provides functionality which is natively included in Node.js, and therefore the native JSON.parse() should be used, for both performance and security reasons.
