Description

This security bulletin contains information about 2 vulnerabilities.


1) Path traversal (CVE-ID: CVE-2025-62156)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote user to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences within the unpack() function. A remote user can upload a specially crafted .zip archive to the application and overwrite arbitrary files on the system outside of the allowed directory. 


2) Insufficiently protected credentials (CVE-ID: CVE-2025-62157)

CWE-ID: CWE-522 - Insufficiently Protected Credentials

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to disclose sensitive information and modify or delete stored artifacts.

The vulnerability exists due to insufficiently protected credentials in workflow-controller logs when handling workflow operations that log artifact repository credentials in plaintext. A remote privileged user can read the workflow-controller pod logs to obtain artifact repository credentials and use them to disclose sensitive information and modify or delete stored artifacts.

Exploitation requires access to read pod logs in a namespace with Argo Workflow.
