Google Cloud says it has fixed a significant security flaw

Google Cloud has patched a vulnerability that may have allowed malicious actors with access to a Kubernetes cluster to elevate their privileges and wreak havoc. 

“An attacker who has compromised the Fluent Bit logging container could combine that access with high privileges required by Anthos Service Mesh (on clusters that have enabled it) to escalate privileges in the cluster,” the company said in an advisory.
