Overview
Affected versions of this package are vulnerable to Arbitrary Code Injection via the EnvoyExtensionPolicy resource. An attacker can execute arbitrary commands and access sensitive credentials by injecting malicious Lua scripts. This can lead to privilege escalation, theft of secrets, and the ability to run or delete resources within the environment.
Workaround
This vulnerability can be mitigated by creating Kubernetes RBAC rules that restrict the creation of these policies to trusted namespaces.
