Impact
Argo CD Cluster secrets might be managed declaratively using Argo CD / kubectl apply. As a result, the full secret body is stored inkubectl.kubernetes.io/last-applied-configuration annotation.
https://github.com/argoproj/argo-cd/pull/7139 introduced the ability to manage cluster labels and annotations. Since clusters are stored as secrets it also exposes the kubectl.kubernetes.io/last-applied-configuration annotation which includes full secret body. In order to view the cluster annotations via the Argo CD API, the user must have clusters, get RBAC access.
Note: In many cases, cluster secrets do not contain any actually-secret information. But sometimes, as in bearer-token auth, the contents might be very sensitive.
Patches
The bug has been patched in the following versions:
- 2.8.3
- 2.7.14
- 2.6.15
Workarounds
Update/Deploy cluster secret with server-side-apply flag which does not use or rely on kubectl.kubernetes.io/last-applied-configuration annotation. Note: annotation for existing secrets will require manual removal.

The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a low impact on the availability of the system.
Active exploitation in the wild has been confirmed. Immediate patching or mitigation is required.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
