2. Release Notes

The following list summarizes the additions, changes, and modifications which were made to Ansible Tower 3.2.5.

2.1. Ansible Tower Version 3.2.5

  • Fixed a RabbitMQ configuration issue that would affect cluster recovery on network interruptions

  • Fixed Tower to disable usage of Jinja templates in launch-time variables for security reasons (CVE-2018-1104). This release introduces the ALLOW_JINJA_IN_EXTRA_VARS configuration parameter for Tower. This parameter has three values: template to allow usage of Jinja saved directly on a job template definition (the default), never to disable all Jinja usage (recommended), and always to always allow Jinja (strongly discouraged, but an option for prior compatibility).

  • Fixed an outstanding issue regarding variable precedence so that the variable value is derived from the survey (survey variables take precedence over Job Template variables).
