medium Tenable Self-Hosted Container Security Plugin ID 421306

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Versions of the package sinatra from 0.0.0 are vulnerable to Reliance on Untrusted Inputs in a Security
 Decision via the X-Forwarded-Host (XFH) header. When making a request to a method with redirect applied,
 it is possible to trigger an Open Redirect Attack by inserting an arbitrary address into this header. If
 used for caching purposes, such as with servers like Nginx, or as a reverse proxy, without handling the
 X-Forwarded-Host header, attackers can potentially exploit Cache Poisoning or Routing-based SSRF.
