CVE-2024-12401 is a medium-severity vulnerability rated 4.4/10 on the CVSS scale. A flaw was found in the cert-manager package. This flaw allows an attacker who can modify PEM data that the cert-manager reads, for example, in a Secret resource, to use large amounts of CPU in the cert-manager controller pod to effectively create a denial-of-service (DoS) vector for the cert-manager in the cluster.. EPSS estimates a 0.63% chance of exploitation in the next 30 days.
