Oracle Linux: CVE-2024-21510: ELSA-2024-10987: pcs security update (MODERATE)

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.
A flaw was found in Sinatra. This vulnerability allows an Open Redirect attack via the X-Forwarded-Host (XFH) header, potentially enabling Cache Poisoning or Server-Side Request Forgery (SSRF) when used in caching servers or reverse proxies.
