Doc Text:
A flaw was found in Puppet resource_api. This vulnerability occurs because the resource-api does not properly preserve the sensitive flag on parameters. As a result, sensitive information, such as passwords, can be stored in cleartext within the agent's local transaction state cache. This could allow an attacker with access to the agent's cache to retrieve sensitive data.

Description OSIDB Bzimport 2026-07-03 08:01:33 UTC
Puppet resource_api (shipped in Puppet Core 8.x and Puppet Enterprise 2023.8.x and 2025.x) does not preserve the sensitive flag on parameters defined via the resource-api, causing values such as passwords to be stored in cleartext in the agent's local transaction state cache. Affected versions of the resource_api module include all versions between 1.5.0 - 1.9.1 and 2.0.0 The issue was fixed in puppet resource_apiĀ 1.9.2 and 2.0.1 released with Puppet Core 8.20.0 and PE 2023.8.10 & PE 2025.11.0.
