{"id":"CVE-2025-62156","state":"PUBLISHED","title":"argo-workflows Zip Slip path traversal allows arbitrary file write and container configuration overwrite","description":"Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes. 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.","publishedAt":"2025-10-14T14:52:44.502Z","updatedAt":"2025-10-14T16:04:24.519Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["argoproj argo-workflows"],"affected":[{"vendor":"argoproj","product":"argo-workflows","versions":[{"version":"< 3.6.12","status":"affected"},{"version":">= 3.7.0, < 3.7.3","status":"affected"}]}],"references":["https://github.com/argoproj/argo-workflows/security/advisories/GHSA-p84v-gxvw-73pf","https://github.com/argoproj/argo-workflows/commit/5659ad9b641fcf52c04ed594cd6493f9170f6011","https://github.com/argoproj/argo-workflows/commit/9f6bc5d236cd1b24d607943384511d71ad17a4c3","https://github.com/argoproj/argo-workflows/blob/946a2d6b9ac3309371fe47f49ae94c33ca7d488d/workflow/executor/executor.go#L993"],"weaknesses":["CWE-22"],"ingestedAt":"2026-10-29T20:09:48.677Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/62xxx/CVE-2025-62156.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-62156","state":"PUBLISHED","datePublished":"2025-10-14T14:52:44.502Z","dateUpdated":"2025-10-14T16:04:24.519Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-10-07T16:12:03.424Z"},"containers":{"cna":{"title":"argo-workflows Zip Slip path traversal allows arbitrary file write and container configuration overwrite","descriptions":[{"lang":"en","value":"Argo Workflows is an open source container-native workflow engine for orchestrating parallel jobs on Kubernetes.
