CVE-2025-62156: argo-workflows Zip Slip path traversal allows arbitrary file write and container configuration overwrite

HighCVSS 8.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 35/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.60% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: github.com/argoproj/argo-workflows/v3 (Go) 3.7.3, 3.6.12.

Low priority for now. Upgrade to github.com/argoproj/argo-workflows/v3 (Go) 3.7.3, 3.6.12 or later.

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.
