CVE-2022-39395 | Vela Insecure Defaults

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 metrics for this CVE.

Base score Version Severity Vector Exploitability Impact Score source
9.6 3.1 CRITICAL
CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H Click to expand
Attack vector (AV:A)
Attacker has to be nearby on the network—same office, same link, that vibe—not the whole wide internet.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.

9.9 3.1 CRITICAL
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
