How to Fix GHSA-v4x8-gw49-7hv4

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

swagger-injector fixed: Latest secure release 
npm install swagger-injector@Latest secure release
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 swagger-injector

How to Check if You Are Affected

To determine whether your Node.js application is affected by GHSA-v4x8-gw49-7hv4, inspect your project dependencies using npm:

npm ls swagger-injector

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

Note: The npm ls swagger-injector 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 Swagger injector, 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

All versions of `swagger-injector` are vulnerable to Path Traversal. The package fails to sanitize URLs, allowing attackers to access server files outside of the configured `dist` folder using relative paths. ## Recommendation No fix is currently available. Consider using an alternative package until a fix is made available.
