CVE-2026-1531
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
Summary
A flaw was found in foreman_kubevirt. When configuring the connection to OpenShift, the system disables SSL verification if a Certificate Authority (CA) certificate is not explicitly set. This insecure default allows a remote attacker, capable of intercepting network traffic between Satellite and OpenShift, to perform a Man-in-the-Middle (MITM) attack. Such an attack could lead to the disclosure or alteration of sensitive information.

Weaknesses
- CWE-295: Improper Certificate Validation
Workarounds
To mitigate this issue, ensure that a Certificate Authority (CA) certificate is explicitly configured when setting up the connection to OpenShift in foreman_kubevirt. This will enable SSL verification and prevent Man-in-the-Middle attacks. Refer to the foreman_kubevirt documentation for specific instructions on configuring CA certificates. A restart or service reload may be required for the changes to take effect.
