CVE-2022-21672 affects the make-ca utility (versions 0.9 to 1.9), which misinterprets Mozilla certdata.txt, causing explicitly untrusted certificates to be treated as trusted. This medium-severity vulnerability (CVSS 6.5) allows a remote attacker to perform a Man-in-the-Middle (MITM) attack by exploiting these previously compromised certificates, leading to high integrity impact. There is no evidence of active exploitation, public exploit code, or significant community discussion, and it is not listed in CISA's KEV catalog. Users are advised to upgrade to make-ca-1.10 and run 'make-ca -f -g' as root immediately.
