Executive Summary

The vulnerability in Puppet resource_api (used in Puppet Core 8.x and Puppet Enterprise 2023.8.x and 2025.x) is that it does not preserve the sensitive flag on parameters defined via the resource-api.

Because of this, sensitive values such as passwords are stored in cleartext within the agent's local transaction state cache.

This issue affects all versions of the resource_api module between 1.5.0 and 1.9.1, as well as version 2.0.0, and was fixed in versions 1.9.2 and 2.0.1.

Impact Analysis

This vulnerability can lead to sensitive information, such as passwords, being stored in cleartext on the local machine running the Puppet agent.

If an attacker gains access to the agent's local transaction state cache, they could retrieve these sensitive values, potentially compromising system security.

Mitigation Strategies

To mitigate this vulnerability, upgrade the puppet resource_api module to version 1.9.2 or 2.0.1 or later.

Ensure you are running Puppet Core 8.20.0 or later, or Puppet Enterprise versions 2023.8.10 or 2025.11.0 or later, where the fix has been applied.
