CVE-2023-23947  (opens in a new tab)
CWE-285  (opens in a new tab)

How to fix?

Upgrade github.com/argoproj/argo-cd/v2/server to version 2.3.17, 2.4.23, 2.5.11, 2.6.2 or higher.

Overview

Affected versions of this package are vulnerable to Improper Authorization by allowing allows users who have the ability to update at least one cluster secret to update any cluster secret. The attacker could use this access to escalate privileges (potentially controlling Kubernetes resources) or to break Argo CD functionality (by preventing connections to external clusters).

Note: To take advantage of the vulnerability, an attacker must know the server URL for the cluster secret they want to modify.

Workaround

Users who are unable to upgrade to the fixed version should:

  1. Limit Users with Cluster Update Access

  2. Restrict Resource Management via AppProjects and RBAC
