Overview
github.com/traefik/traefik/v2/api is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy.
Affected versions of this package are vulnerable to Open Redirect. There exists a potential open redirect vulnerability in Traefik's handling of the X-Forwarded-Prefix
header. The Traefik API dashboard component doesn't validate that the value of the header X-Forwarded-Prefix
is a site relative path and will redirect to any header provided URI. Successful exploitation of an open redirect can be used to entice victims to disclose sensitive information. Active Exploitation of this issue is unlikely as it would require active header injection, however, the Traefik team addressed this issue nonetheless to prevent abuse in e.g. cache poisoning scenarios.
