CVE-2021-27225
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn Dataiku DSS before 8.0.6, insufficient access control in the Jupyter notebooks integration allows users (who have coding permissions) to read and overwrite notebooks in projects that they are not authorized to access.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceDataiku DSS before version 8.0.6 contains an insufficient access control vulnerability in its Jupyter notebooks integration. Users who have coding permissions can read and overwrite notebooks in projects they are not authorized to access, allowing unauthorized data access and modification across project boundaries.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Dataiku DSS versionLocate the Dataiku installation directory and find the version file or run the version command (typically dss --version or check the About section in the web interface). Compare the version number to the affected range (anything below 8.0.6).Affected if The installed version is less than 8.0.6
-
Verify Jupyter notebooks integration is enabledCheck the Dataiku DSS configuration for Jupyter notebook integration settings. This is typically found in the installation directory under dataiku/config or through the Administration > Settings > Jupyter section in the web UI.Affected if Jupyter notebooks integration is active and users have access to create or edit notebooks
-
Identify users with coding permissionsReview user permissions in Dataiku DSS Administration > Security > Users. Look for users assigned to groups with 'coding' or 'write' permissions on any project.Affected if There exist users with coding permissions (not restricted to specific projects) who could potentially access notebooks across project boundaries
-
Check project-level notebook access controlsNavigate to each project's Security settings and review which users or groups have access to the Jupyter notebooks feature within that project.Affected if Users with coding permissions are granted access to projects they should not have access to, or there are no strict project-level restrictions on notebook access
You are affected if Dataiku DSS version is below 8.0.6, Jupyter notebooks integration is enabled, and users exist with coding permissions that can potentially跨 project boundaries access notebooks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data8.0.6
Upgrade Dataiku DSS to version 8.0.6 or later. Additionally, review and audit user coding permissions to ensure least-privilege access controls are in place across projects.
