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 github.com/traefik/traefik/v2/integration
to version 2.11.9 or higher.
Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity through the manipulation of HTTP headers in the HTTP/1.1 protocol. An attacker can alter or remove headers such as X-Forwarded-Host
, potentially leading to security implications like access control bypass or data leakage by specifying these headers as hop-by-hop in the Connection header.
Note:
This is only exploitable if the backend application trusts the headers set by Traefik without revalidating them.
