- Affected
- npm trailing-slash < 2.0.1
- Fixed in
- 2.0.1· Vendor fix available
- Issue
- The package trailing-slash before 2.0.1 are vulnerable to Open Redirect via the use of trailing double slashes in the URL when accessing the vulnerable endpoint (such as https://example.com//attacker.example/). The vulnerable code is in index.js::createTrailing(), as the web server uses relative URLs instead of absolute URLs.
Recommended action: Upgrade to 2.0.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
