How to Fix GHSA-rrqv-vjrw-hrcr

To remediate this vulnerability, upgrade all affected Json ptr dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

json-ptr fixed: 2.1.0 
npm install json-ptr@2.1.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls json-ptr

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-rrqv-vjrw-hrcr, inspect your project dependencies using npm:

npm ls json-ptr

Analyze the terminal output to locate any version of Json ptr in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1.0), your application is affected.

Note: The npm ls json-ptr command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Json ptr, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

There is a security vulnerability in `json-ptr` versions prior to v2.1.0 in which an unscrupulous actor may execute arbitrary code. If your code sends un-sanitized user input to json-ptr's .get() method, your project is vulnerable to this injection-style vulnerability.
