{"id":"CVE-2026-113708","published":"2026-10-20T19:17:33Z","modified":"2026-10-20T19:59:00Z","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 2.7.0 until 3.3.15, 3.4.10, 3.5.4, and 3.6.0-rc2, Kustomize passes ref or version query values from remote resource, base, or component URLs to git fetch without an end-of-options separator. A leading-hyphen value can be parsed as --upload-pack and execute a command inside argocd-repo-server when the remote uses a local transport such as file://. Git does not run the supplied command for an https:// remote. The local transport does not leave the pod, so blocking repo-server egress does not prevent the execution. The command runs as the repo-server user, can read repository credentials and other process-accessible data, and can return output through manifest-generation errors. An attacker can commit a Kustomization to a Git repository that an Application builds or upload 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. Kustomize 5.0.0 introduced acceptance of file://, whereas 4.5.7 rejects that transport; replacing the affected Kustomize with a newer version alone does not correct the missing option separator. 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":0.00666,"percentile":0.5182,"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-88","name":"Improper Neutralization of Argument Delimiters in a Command"}],"references":[{"url":"https://argo-cd.readthedocs.io/en/stable/user-guide/kustomize/#custom-kustomize-versions","tags":[]},{"url":"https://github.com/argoproj/argo-cd/commit/25badeb7a1e154805340bb7237e0ce671f3772dd","tags":[]},{"url":"https://github.com/argoproj/argo-cd/pull/12299","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-9v9p-x54c-58gc","tags":[]},{"url":"https://github.com/argoproj/argo-cd/security/advisories/GHSA-j6cw-g6p4-7hch","tags":[]}],"techniques":[],"reports":[],"affected":[],"advisories":[],"euvd":{"id":"EUVD-2026-105249","url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-105249","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-2026-113708","provenance":"source"}],"speed":{"daysToPublicExploit":null,"firstExploitFrom":null,"daysToKev":null},"priority":{"score":19.2,"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":10.36,"detail":"percentile 0.5182"},{"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-2026-113708","relation":"related","confidence":"high","kind":"lineage","evidence":[{"kind":"osv-related","provenance":"source","id":"GHSA-j6cw-g6p4-7hch","via":"related"}]}],"children":[{"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"}]}]}}
