How to Fix CVE-2019-5479

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

larvitbase-api fixed: 0.5.5 
npm install larvitbase-api@0.5.5
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 larvitbase-api

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2019-5479, inspect your project dependencies using npm:

npm ls larvitbase-api

Analyze the terminal output to locate any version of Larvitbase api in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.5.5), your application is affected.

Note: The npm ls larvitbase-api 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-829: Inclusion of Functionality from Untrusted Control Sphere, where the product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere. In Larvitbase api, 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 `larvitbase-api` prior to 0.5.4 are vulnerable to an Unintended Require. The package exposes an API endpoint and passes a GET parameter unsanitized to an `require()` call. This allows attackers to execute any `.js` file in the same folder as the server is running. ## Recommendation Upgrade to version 0.5.4 or later.
