{"id":"CVE-2026-113709","published":"2026-10-20T19:17:33Z","modified":"2026-10-21T16:17:24Z","title":"Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes","vendor":"argoproj","product":"argo-cd","tier":"core","eol":null,"description":{"text":"Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. 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.","provenance":"source","from":"NVD"},"summary":null,"cvss":{"score":9.9,"severity":"CRITICAL","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","provenance":"source","from":"NVD"},"epss":{"score":0.0053,"percentile":0.44836,"date":"2026-10-30","provenance":"source"},"kev":null,"vulncheckKev":null,"exploited":false,"otx":{"pulseCount":6,"pulses":[{"name":"Known_Cve | Oct 29, 2026 | Part 1/3","url":"https://otx.alienvault.com/pulse/6ae20c23cd267c7cddd4e545","created":"2026-10-28"},{"name":"Known_Cve | Oct 28, 2026 | Part 1/3","url":"https://otx.alienvault.com/pulse/6ae0ba88997d8920e9952075","created":"2026-10-27"},{"name":"Known_Cve | Oct 27, 2026 | Part 1/3","url":"https://otx.alienvault.com/pulse/6adf68beabc3bad24a2b7cc6","created":"2026-10-26"},{"name":"Known_Cve | Oct 24, 2026 | Part 2/3","url":"https://otx.alienvault.com/pulse/6adb741adaae4be68dd04fea","created":"2026-10-23"},{"name":"Known_Cve | Oct 23, 2026 | Part 2/3","url":"https://otx.alienvault.com/pulse/6ada237de8198eb6a6cbfac4","created":"2026-10-22"},{"name":"Known_Cve | Oct 22, 2026 | Part 3/4","url":"https://otx.alienvault.com/pulse/6ad8d34cb141a6cceeba88be","created":"2026-10-21"}],"provenance":"machine"},"cwes":[{"id":"CWE-829","name":"Inclusion of Functionality from Untrusted Control Sphere"}],"references":[{"url":"https://argo-cd.readthedocs.io/en/stable/user-guide/kustomize/#kustomizing-helm-charts","tags":[]},{"url":"https://github.com/argoproj/argo-cd/commit/b6d5c23bce2f8a46c52975ba438a3b93d242d96c","tags":[]},{"url":"https://github.com/argoproj/argo-cd/pull/6059","tags":[]},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.3.15","tags":[]},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.4.10","tags":[]},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.5.4","tags":[]},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.6.0-rc2","tags":[]},{"url":"https://github.com/argoproj/argo-cd/security/advisories/GHSA-fw5c-w8rc-j7fx","tags":[]},{"url":"https://github.com/argoproj/argo-cd/security/advisories/GHSA-j6cw-g6p4-7hch","tags":[]},{"url":"https://github.com/kubernetes-sigs/kustomize/pull/3784","tags":[]}],"techniques":[],"reports":[],"affected":[],"advisories":[],"euvd":{"id":"EUVD-2026-105250","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-105250","exploited":false,"exploitedSince":null,"provenance":"source"},"exploits":[],"exploitSources":null,"exploitRefs":[],"flow":[],"timeline":[{"date":"2026-10-20","kind":"published","label":"Published (NVD)","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-113709","provenance":"source"}],"speed":{"daysToPublicExploit":null,"firstExploitFrom":null,"daysToKev":null},"priority":{"score":17.8,"factors":[{"name":"In a KEV catalog","points":0.0,"detail":"not listed"},{"name":"Recent KEV listing","points":0.0,"detail":"not listed"},{"name":"Known ransomware use","points":0.0,"detail":"not known"},{"name":"EPSS percentile","points":8.97,"detail":"percentile 0.4484"},{"name":"Named in threat reports","points":0.0,"detail":"0 reports"},{"name":"Public exploit code","points":0.0,"detail":"none found"},{"name":"Mentioned in OTX pulses","points":1.92,"detail":"6 pulses"},{"name":"CVSS severity","points":6.93,"detail":"base score 9.9"},{"name":"End-of-life product","points":0.0,"detail":"supported or unknown"}]},"lineage":{"familyId":"fam-argoproj-argo-cd-cve-2026-55797","parents":[{"from":"CVE-2026-55797","to":"CVE-2026-113709","relation":"related","confidence":"high","kind":"lineage","evidence":[{"kind":"osv-related","provenance":"source","id":"GHSA-j6cw-g6p4-7hch","via":"related"}]},{"from":"CVE-2026-113708","to":"CVE-2026-113709","relation":"related","confidence":"medium","kind":"lineage","evidence":[{"kind":"same-code","provenance":"machine","files":["hack/tool-versions.sh"],"commits":["https://github.com/argoproj/argo-cd/commit/25badeb7a1e154805340bb7237e0ce671f3772dd","https://github.com/argoproj/argo-cd/commit/b6d5c23bce2f8a46c52975ba438a3b93d242d96c"],"basis":"rarely changed file"}]}]}}
