Summary

CVE-2023-40029 is a vulnerability affecting Argo CD, a declarative continuous deployment tool for Kubernetes. The vulnerability allows an attacker to access sensitive information stored in the `kubectl.kubernetes.io/last-applied-configuration` annotation, which includes the full secret body of cluster secrets. This can pose a significant danger to organizations, especially if the secrets contain sensitive information like bearer-token authentication details. The bug has been patched in versions 2.8.3, 2.7.14, and 2.6.15, and users are advised to upgrade to these versions. Alternatively, users who are unable to upgrade should update/deploy cluster secrets with the `server-side-apply` flag to avoid relying on the vulnerable annotation. The severity of this vulnerability is rated as CRITICAL with a base score of 9.9 out of 10 according to the Common Vulnerability Scoring System (CVSS).
