Impact
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.

This leads to cross-namespace privilege escalation, impacting application integrity through unauthorized application updates.
