What is CVE-2023-40029?

Argo CD, a continuous deployment tool for Kubernetes, exposes potentially sensitive information through the kubectl.kubernetes.io/last-applied-configuration annotation. This issue arises when cluster secrets are managed declaratively, which can unintentionally store sensitive data, such as bearer tokens, in locations accessible by users with specific RBAC permissions. It is crucial for users to upgrade to the patched versions (2.8.3, 2.7.14, and 2.6.15) or apply best practices by deploying secrets with the server-side-apply flag to mitigate this risk effectively.
