CWE-113  (opens in a new tab)

How to fix?

Upgrade RHEL:8 openshift-clients to version 0:4.14.0-202311031050.p0.g9b1e0d2.assembly.stream.el8 or higher.
This issue was patched in RHSA-2023:6840.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift-clients package and not the openshift-clients package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

The HTTP/1 client does not fully validate the contents of the Host header. A maliciously crafted Host header can inject additional headers or entire requests. With fix, the HTTP/1 client now refuses to send requests containing an invalid Request.Host or Request.URL.Host value.
