CVE-2021-27024
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 · uneditedA flaw was discovered in Continuous Delivery for Puppet Enterprise (CD4PE) that results in a user with lower privileges being able to access a Puppet Enterprise API token. This issue is resolved in CD4PE 4.10.0
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 · moderate confidenceA privilege escalation vulnerability in Continuous Delivery for Puppet Enterprise (CD4PE) allows users with lower privileges to access Puppet Enterprise API tokens they should not have access to, enabling potential unauthorized actions within the PE environment.

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 CD4PE versionLog into the CD4PE web interface and navigate to Settings > About, or run 'cd4pe --version' from the command line if availableAffected if The installed version is lower than 4.10.0 (for example, 4.9.x, 4.8.x, etc.)
-
Verify CD4PE is integrated with Puppet EnterpriseIn the CD4PE web UI, go to Settings > Puppet Enterprise and confirm a PE connection is configured. Check if the 'PE token' or 'PE connection' settings are present and active.Affected if CD4PE is connected to a Puppet Enterprise instance and uses PE API tokens for authentication
-
Identify lower-privileged CD4PE usersIn CD4PE, navigate to Settings > Users or Access Control and review user roles. Look for users with roles other than 'Administrator' or 'Owner'Affected if There are users assigned to non-administrative roles (such as Viewer, Deployer, or Pipeline Editor) in the CD4PE environment
-
Review PE API token access logsCheck CD4PE audit logs or PE console logs for API token access events. Look for token retrieval or usage by non-administrative user accountsAffected if Non-administrative users have accessed or retrieved Puppet Enterprise API tokens they were not authorized to use
You are affected if CD4PE version is lower than 4.10.0 AND CD4PE is connected to Puppet Enterprise, allowing lower-privileged users potential access to PE API tokens.

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.
dbcve · scoped4.10.0
Upgrade CD4PE to version 4.10.0 or later to remediate this vulnerability. If immediate upgrade is not possible, restrict lower-privileged user access to CD4PE until the patch can be applied.
4.10.0
- Backup your current Continuous Delivery for Puppet Enterprise (CD4PE) installation and configuration
- Upgrade CD4PE to version 4.10.0 or later
- After upgrade, verify that users with lower privileges can no longer access Puppet Enterprise API tokens
- Confirm normal CD4PE functionality is restored post-upgrade
