CVE-2023-23947: Argo CD users with any cluster secret update access may update out-of-bounds cluster secrets
First published: Tue Feb 07 2023(Updated: )
A flaw was found in ArgoCD. An improper authorization bug may allow an attacker to update at least one cluster secret, enabling them to change any other cluster secret. The attacker must know the URL for the targeted cluster and additionally it should be authenticated within the ArgoCD API server with enough privileges to update at least one cluster. A successful attack may lead to privilege escalations or denial of service.
