How to Fix GHSA-724c-6vrf-99rq

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

loopback fixed: 2.42.0 
npm install loopback@2.42.0
loopback fixed: 3.26.0 
npm install loopback@3.26.0
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 loopback

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-724c-6vrf-99rq, inspect your project dependencies using npm:

npm ls loopback

Analyze the terminal output to locate any version of Loopback in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.42.0), your application is affected.

Note: The npm ls loopback 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-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Loopback, 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

Versions of `loopback` prior to 3.26.0 (3.x) and 2.42.0 (2.x) are vulnerable to Sensitive Data Exposure. Invalid API requests to the login endpoint may return information about the first user in the database. This can be used alongside other attacks for credential theft. ## Recommendation If you're using `loopback` 3.x upgrade to version 3.26.0 or later. If you're using `loopback` 2.x upgrade to version 2.42.0 or later.
