{"cve":"CVE-2025-66626","nvd":{"published":"2025-12-09T21:16:00.150","modified":"2026-10-14T21:10:00.183","status":"Analyzed","description":"Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. Versions 3.6.13 and below and versions 3.7.0 through 3.7.4, contain unsafe untar code that handles symbolic links in archives. Concretely, the computation of a link's target and the subsequent check are flawed. An attacker can overwrite the file /var/run/argo/argoexec with a script of their choice, which would be executed at the pod's start. The patch deployed against CVE-2025-62156 is ineffective against malicious archives containing symbolic links. This issue is fixed in versions 3.6.14 and 3.7.5.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-59","CWE-23","CWE-78"],"references":["https://github.com/advisories/GHSA-p84v-gxvw-73pf","https://github.com/argoproj/argo-workflows/blob/5291e0b01f94ba864f96f795bb500f2cfc5ad799/workflow/executor/executor.go#L1034-L1037","https://github.com/argoproj/argo-workflows/commit/6b92af23f35aed4d4de8b04adcaf19d68f006de1","https://github.com/argoproj/argo-workflows/security/advisories/GHSA-xrqc-7xgx-c9vh","https://github.com/advisories/GHSA-p84v-gxvw-73pf"],"products":["argoproj:argo_workflows"],"source":"nvd","synced_at":"2026-10-19T22:16:40.427100871+00:00"},"epss":{"cve":"CVE-2025-66626","score":0.0068,"percentile":0.52111,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-xrqc-7xgx-c9vh","url":"https://osv.dev/vulnerability/GHSA-xrqc-7xgx-c9vh","summary":" RCE via ZipSlip and symbolic links in argoproj/argo-workflows","modified":"2026-09-10T03:50:32.335587199Z","packages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-workflows/v3","purl":"pkg:golang/github.com/argoproj/argo-workflows/v3","ranges":[">=3.7.0 <3.7.5"],"fixed":["3.7.5"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-workflows/v3","purl":"pkg:golang/github.com/argoproj/argo-workflows/v3","ranges":["<3.6.14"],"fixed":["3.6.14"]},{"ecosystem":"Go","name":"github.com/argoproj/argo-workflows","purl":"pkg:golang/github.com/argoproj/argo-workflows","ranges":["<=2.5.3-rc4"],"fixed":[]}]},{"id":"GO-2025-4223","url":"https://osv.dev/vulnerability/GO-2025-4223","summary":"RCE via ZipSlip and symbolic links in argoproj/argo-workflows in github.com/argoproj/argo-workflows","modified":"2026-02-04T02:59:19.565247Z","packages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-workflows","purl":"pkg:golang/github.com/argoproj/argo-workflows","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/argoproj/argo-workflows/v2","purl":"pkg:golang/github.com/argoproj/argo-workflows/v2","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/argoproj/argo-workflows/v3","purl":"pkg:golang/github.com/argoproj/argo-workflows/v3","ranges":["<3.6.14",">=3.7.0 <3.7.5"],"fixed":["3.6.14","3.7.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
