🚨Critical - Argo CD Repo-Server RCE via Kustomize (CVE-2026-113708 + CVE-2026-113709) In argocd-repo-server, two critical issues: Kustomize remote refs (file://) pass unsanitized ref/version values to git fetch, allowing leading-hyphen commands to execute as the repo-server user. With --enable-helm, helmGlobals.configHome can point to a repo-controlled path; a plugin:// helmCharts URL then auto-loads and runs a malicious Helm downloader plugin. Both grant RCE + access to repo credentials/data. Setups not using --enable-helm are unaffected by the second issue. 👉Affected: argo-cd (http://github.com/argoproj/argo-cd/v2, /v3) versions with kustomize --enable-helm enabled
