CVE-2023-48713
An attacker who controls a pod to a degree where they can control the responses from the /metrics endpoint can cause Denial-of-Service of the autoscaler from an unbound memory allocation bug.
Does this matter?
Lower severity and a low EPSS score (0.87%). Track it; it rarely justifies an emergency change on its own.
