Argocd-image-updater: argocd image updater: cross-namespace privilege escalation via insufficient namespace validation
Description
A flaw was found in ArgoCD Image Updater. This vulnerability allows an attacker, with permissions to create or modify an ImageUpdater resource in a multi-tenant environment, to bypass namespace boundaries.
