{"schemaVersion":3,"id":"CVE-2026-113709","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"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.","dates":{"published":"2026-10-20T18:08:36.565Z","modified":"2026-10-20T18:08:36.565Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":9.9,"severity":"critical","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":9.9,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":9.9,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-829","name":"Inclusion of Functionality from Untrusted Control Sphere","description":"The product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere.","type":"weakness","status":"Incomplete","abstraction":"Base","likelihoodOfExploit":null,"url":"https://cwe.mitre.org/data/definitions/829.html"}],"affected":[{"vendor":"argoproj","product":"argo-cd","name":"argo-cd","label":"argo-cd","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"≥ 2.1.0, < 3.3.15","noFixRecorded":false,"fixedIn":null},{"text":"≥ 3.4.0-rc1, < 3.4.10","noFixRecorded":false,"fixedIn":null},{"text":"≥ 3.5.0-rc1, < 3.5.4","noFixRecorded":false,"fixedIn":null},{"text":"≥ 3.6.0-rc1, < 3.6.0-rc2","noFixRecorded":false,"fixedIn":null}],"versionsText":"≥ 2.1.0, < 3.3.15 | ≥ 3.4.0-rc1, < 3.4.10 | ≥ 3.5.0-rc1, < 3.5.4 | ≥ 3.6.0-rc1, < 3.6.0-rc2","eol":{"isEol":null,"eolDate":null,"matchMethod":"name_exact","cycle":null,"product":{"name":"argo-cd","label":"Argo CD","category":"server-app"}},"hubHref":"/vendor/argoproj/argo-cd"}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://github.com/argoproj/argo-cd/security/advisories/GHSA-fw5c-w8rc-j7fx","label":"github.com/argoproj/argo-cd/security/advisories/GHSA-fw5c-w8rc-j7fx","hostname":"github.com","tags":["X Refsource CONFIRM"]},{"url":"https://github.com/argoproj/argo-cd/security/advisories/GHSA-j6cw-g6p4-7hch","label":"github.com/argoproj/argo-cd/security/advisories/GHSA-j6cw-g6p4-7hch","hostname":"github.com","tags":["X Refsource MISC"]},{"url":"https://github.com/argoproj/argo-cd/pull/6059","label":"github.com/argoproj/argo-cd/pull/6059","hostname":"github.com","tags":["X Refsource MISC"]},{"url":"https://github.com/kubernetes-sigs/kustomize/pull/3784","label":"github.com/kubernetes-sigs/kustomize/pull/3784","hostname":"github.com","tags":["X Refsource MISC"]},{"url":"https://github.com/argoproj/argo-cd/commit/b6d5c23bce2f8a46c52975ba438a3b93d242d96c","label":"github.com/argoproj/argo-cd/commit/b6d5c23bce2f8a46c52975ba438a3b93d242d96c","hostname":"github.com","tags":["X Refsource MISC"]},{"url":"https://argo-cd.readthedocs.io/en/stable/user-guide/kustomize/#kustomizing-helm-charts","label":"argo-cd.readthedocs.io/en/stable/user-guide/kustomize/","hostname":"argo-cd.readthedocs.io","tags":["X Refsource MISC"]},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.3.15","label":"github.com/argoproj/argo-cd/releases/tag/v3.3.15","hostname":"github.com","tags":["X Refsource MISC"]},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.4.10","label":"github.com/argoproj/argo-cd/releases/tag/v3.4.10","hostname":"github.com","tags":["X Refsource MISC"]},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.5.4","label":"github.com/argoproj/argo-cd/releases/tag/v3.5.4","hostname":"github.com","tags":["X Refsource MISC"]},{"url":"https://github.com/argoproj/argo-cd/releases/tag/v3.6.0-rc2","label":"github.com/argoproj/argo-cd/releases/tag/v3.6.0-rc2","hostname":"github.com","tags":["X Refsource MISC"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-20T18:08:36.565Z","label":"Published","detail":"Vulnerability first disclosed.","source":null}],"risk":{"score":70,"level":"high","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-21T03:15:51.108Z","stale":false,"partial":false}}
