Potential forgery of webhook requests when using a unauthenticated webhook in SUSE Rancher Fleet 0.15 before 0.15.2, 0.14 before 0.14.6, 0.13 before 0.13.11 and 0.12 before 0.12.5 could be used by remote attackers to cause a denial of service or a downgrade attack on other repositories on the system.
Weakness
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
