CVE-2023-48713: Knative Serving

Medium severity, CVSS 5.3. EPSS: 0.9% chance of exploitation in the next 30 days.

Knative Serving builds on Kubernetes to support deploying and serving of applications and functions as serverless containers. 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. This is a DoS vulnerability, where a non-privileged Knative user can cause a DoS for the cluster. This issue has been patched in version 0.39.0.

Affected products

• Knative Serving: before 1.10.5 (fixed in 1.10.5); from 1.11.0, before 1.11.3 (fixed in 1.11.3)
