Unknown · Argo Workflows · CVE-2025-66626
**Name of the Vulnerable Software and Affected Versions**
Argo Workflows versions 3.6.13 and below
Argo Workflows versions 3.7.0 through 3.7.4
**Description**
Argo Workflows, a container-native workflow engine for Kubernetes, has an issue with unsafe untar code that improperly handles symbolic links within archives. A flaw exists in how a link's target is calculated and checked. This allows an attacker to overwrite the file `/var/run/argo/argoexec` with a malicious script, which would then be executed when the pod starts. The previously deployed patch is ineffective against archives containing malicious symbolic links.
**Recommendations**
Update to Argo Workflows version 3.6.14 or later.
Update to Argo Workflows version 3.7.5 or later.
