Versions prior to 3.6.12 and versions 3.7.0 through 3.7.2 contain a Zip Slip path traversal vulnerability in artifact extraction. During artifact extraction the unpack/untar logic (workflow/executor/executor.go) uses filepath.Join(dest, filepath.Clean(header.Name)) without validating that header.Name stays within the intended extraction directory. A malicious archive entry can supply a traversal or absolute path that, after cleaning, overrides the destination directory and causes files to be written outside the /work/tmp extraction path and into system directories such as /etc inside the container. The vulnerability enables arbitrary file creation or overwrite in system configuration locations (for example /etc/passwd, /etc/hosts, /etc/crontab), which can lead to privilege escalation or persistence within the affected container. Update to 3.6.12 or 3.7.3 to remediate the issue.","published":"2025-10-14T14:52:44.502Z","modified":"2026-08-12T03:51:16.771640050Z","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H"},"epss":{"score":0.00551,"percentile":0.43614,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/argoproj/argo-workflows/v3","fixedVersion":"3.6.12"},{"ecosystem":"Go","name":"github.com/argoproj/argo-workflows/v3","fixedVersion":"3.7.3"}],"fix":{"url":"https://github.com/argoproj/argo-workflows/commit/5659ad9b641fcf52c04ed594cd6493f9170f6011","label":"argoproj/argo-workflows@5659ad9"},"references":[{"type":"WEB","url":"https://github.com/argoproj/argo-workflows/blob/946a2d6b9ac3309371fe47f49ae94c33ca7d488d/workflow/executor/executor.go#L993"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/62xxx/CVE-2025-62156.json"},{"type":"ADVISORY","url":"https://github.com/argoproj/argo-workflows/security/advisories/GHSA-p84v-gxvw-73pf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-62156"},{"type":"FIX","url":"https://github.com/argoproj/argo-workflows/commit/5659ad9b641fcf52c04ed594cd6493f9170f6011"},{"type":"FIX","url":"https://github.com/argoproj/argo-workflows/commit/9f6bc5d236cd1b24d607943384511d71ad17a4c3"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:16.771640050Z"}}
