CVE-2022-39395 Detail


Vela is a Pipeline Automation (CI/CD) framework built on Linux container technology written in Golang. In Vela Server and Vela Worker prior to version 0.16.0 and Vela UI prior to version 0.17.0, some default configurations for Vela allow exploitation and container breakouts. Users should upgrade to Server 0.16.0, Worker 0.16.0, and UI 0.17.0 to fix the issue. After upgrading, Vela administrators will need to explicitly change the default settings to configure Vela as desired. Some of the fixes will interrupt existing workflows and will require Vela administrators to modify default settings. However, not applying the patch (or workarounds) will continue existing risk exposure. Some workarounds are available. Vela administrators can adjust the worker's `VELA_RUNTIME_PRIVILEGED_IMAGES` setting to be explicitly empty, leverage the `VELA_REPO_ALLOWLIST` setting on the server component to restrict access to a list of repositories that are allowed to be enabled, and/or audit enabled repositories and disable pull_requests if they are not needed.


CVSS 3.x Severity and Metrics:

Base Score:  9.9 CRITICAL
Vector:  CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H

Nist CVSS score does not match with CNA score
CNA:  GitHub, Inc.
Base Score:  9.6 CRITICAL
Vector:  CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H

NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
