{"schemaVersion":3,"id":"CVE-2026-113708","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"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.","dates":{"published":"2026-10-20T18:03:17.219Z","modified":"2026-10-20T18:43:40.767Z","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-88","name":"Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')","description":"The product constructs a string for a command to be executed by a separate component\nin another control sphere, but it does not properly delimit the\nintended arguments, options, or switches within that command string.","type":"weakness","status":"Draft","abstraction":"Base","likelihoodOfExploit":null,"url":"https://cwe.mitre.org/data/definitions/88.html"}],"affected":[{"vendor":"argoproj","product":"argo-cd","name":"argo-cd","label":"argo-cd","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"≥ 2.7.0, < 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":"≥ 2.7.0, < 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-9v9p-x54c-58gc","label":"github.com/argoproj/argo-cd/security/advisories/GHSA-9v9p-x54c-58gc","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/12299","label":"github.com/argoproj/argo-cd/pull/12299","hostname":"github.com","tags":["X Refsource MISC"]},{"url":"https://github.com/argoproj/argo-cd/commit/25badeb7a1e154805340bb7237e0ce671f3772dd","label":"github.com/argoproj/argo-cd/commit/25badeb7a1e154805340bb7237e0ce671f3772dd","hostname":"github.com","tags":["X Refsource MISC"]},{"url":"https://argo-cd.readthedocs.io/en/stable/user-guide/kustomize/#custom-kustomize-versions","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":["CVE-2026-55797"]},"timeline":[{"kind":"published","date":"2026-10-20T18:03:17.219Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-20T18:43:40.767Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":70,"level":"high","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-21T12:45:28.106Z","stale":false,"partial":false}}
