CVE-2021-27024Network attack vector

API token exposure via undisclosed permission flaw

Published Nov 18, 2021 · Updated Aug 3, 2024

Information disclosure in Puppet Continuous Delivery before 4.10.0 allows remote authenticated users to access a Puppet Enterprise API token. Puppet has not published the affected endpoint, function, or permission-check failure that exposes the token to a lower-privileged account. A valid lower-privileged CD4PE account is required; the disclosed consequence is unauthorized possession of a Puppet Enterprise API token.
