https://notcve.org/view.php?id=CVE-2022-0851
29 Aug 2022 — There is a flaw in convert2rhel. When the --activationkey option is used with convert2rhel, the activation key is subsequently passed to subscription-manager via the command line, which could allow unauthorized users locally on the machine to view the activation key via the process command line via e.g. htop or ps. The specific impact varies upon the subscription, but generally this would allow an attacker to register systems purchased by the victim until discovered; a form of fraud. This could occur regard... • https://access.redhat.com/security/cve/CVE-2022-0851 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer •
