npm install restify-swagger-jsdoc@3.2.1
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 restify-swagger-jsdoc

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-gvff-25cc-4f66, inspect your project dependencies using npm:

npm ls restify-swagger-jsdoc

Note: The npm ls restify-swagger-jsdoc 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Restify swagger jsdoc, 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 `restify-swagger-jsdoc` prior to 3.2.1 are vulnerable to Path Traversal. The package fails to properly sanitize URLs, which may allow attackers to access server files outside the `swagger-ui` folder by using relative paths. ## Recommendation Upgrade to version 3.2.1 or later.
