From 2.1.0 until 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2, when an operator has enabled --enable-helm for kustomize build, helmGlobals.configHome can point Helm's config and data directories at a repository-controlled location. Helm automatically loads a downloader plugin from `<configHome>/.data/plugins` without a separate plugin-install step and executes its program inside argocd-repo-server when a helmCharts repository URL uses the plugin's protocol. The command runs as the repo-server user and can read repository credentials and other process-accessible data. An attacker can commit the Kustomization and plugin to a Git repository that an Application builds or upload the files through POST /api/v1/applications/manifestsWithFiles, also exposed by argocd app diff --local --server-side-generate. The upload path requires only Application get permission on an existing Application, without Application update or sync permission or repository write access. Both delivery paths require prior operator enablement of --enable-helm; deployments that do not enable it are not affected. Kustomize 4.1.0 first passed helmGlobals.configHome through to Helm. This issue is fixed in versions 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2.","state":0,"publishedAt":"2026-10-20T18:08:36.565+00:00","modifiedAt":"2026-10-21T15:52:55.778+00:00","affected":[{"ecosystem":"Vendor product","name":"argo-cd","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"argoproj\",\n                    \"product\": \"argo-cd\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.1.0, < 3.3.15\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.4.0-rc1, < 3.4.10\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.5.0-rc1, < 3.5.4\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.6.0-rc1, < 3.6.0-rc2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":"CRITICAL"}],"references":["https://github.com/argoproj/argo-cd/security/advisories/GHSA-fw5c-w8rc-j7fx","https://github.com/argoproj/argo-cd/security/advisories/GHSA-j6cw-g6p4-7hch","https://github.com/argoproj/argo-cd/pull/6059","https://github.com/kubernetes-sigs/kustomize/pull/3784","https://github.com/argoproj/argo-cd/commit/b6d5c23bce2f8a46c52975ba438a3b93d242d96c","https://argo-cd.readthedocs.io/en/stable/user-guide/kustomize/#kustomizing-helm-charts","https://github.com/argoproj/argo-cd/releases/tag/v3.3.15","https://github.com/argoproj/argo-cd/releases/tag/v3.4.10","https://github.com/argoproj/argo-cd/releases/tag/v3.5.4","https://github.com/argoproj/argo-cd/releases/tag/v3.6.0-rc2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-113709","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-113709","identifiers":["CVE-2026-113709"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
