Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Test your applicationsUpgrade trailing-slash
to version 2.0.1 or higher.
trailing-slash is an Add or remove trailing slashes, and redirect.
Affected versions of this package 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.
1. Set up an server endpoint that uses trailing-slashes
2. Append "//example.com" to the endpoint - it should redirect to example.com
