CVE-2021-20180

Description

A flaw was found in ansible module where credentials are disclosed in the console log by default and not protected by the security feature when using the bitbucket_pipeline_variable module. This flaw allows an attacker to steal bitbucket_pipeline credentials. The highest threat from this vulnerability is to confidentiality.

Statement

The version of Ansible provided in Red Hat Gluster Storage 3 does not contain the vulnerable bitbucket module and is not affected by this vulnerability. However, Red Hat Gluster Storage 3 no longer maintains its own version of Ansible. The prerequisite is to enable the Ansible repository in order to consume the latest version of Ansible, which includes bug and security fixes.
