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.

Affected versions of this package are vulnerable to Open Redirect through the X-Forwarded-Host

), it is always accepted as the actual host of that request.
Since this host is used for all url helpers, an attacker could change generated links and redirects.
