CRITICAL 9.6DOWNGRADE

CVE-2023-50253 is a critical-severity flaw (CVSS 9.6) affecting laf. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Laf is a cloud development platform. In the Laf version design, the log uses communication with k8s to quickly retrieve logs from the container without the need for additional storage. However, in version 1.0.0-beta.13 and prior, this interface does not verify the permissions of the pod, which allows authenticated users to obtain any pod logs under the same namespace through this method, thereby obtaining sensitive information printed in the logs
