argo-workflows Zip Slip path traversal allows arbitrary file write and container configuration overwrite

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.

对路径名的限制不恰当(路径遍历)

Argo Workflows 路径遍历漏洞

Argo Workflows是Argo项目的一个用于 Kubernetes 的开源容器原生工作流引擎。 Argo Workflows 3.6.12之前版本和3.7.0版本至3.7.2版本存在路径遍历漏洞，该漏洞源于artifact extraction中存在Zip Slip路径遍历漏洞，可能导致任意文件创建或覆盖。
