What's new

Here's what's new in each version of the Splunk Add-on Builder.

Note: If you use the Add-on Builder to build add-ons for the Splunk Cloud Platform, make sure to review the latest information changes and requirements for the Splunk Cloud Platform.

Version 4.1.4

Version 4.1.4 of the Splunk Add-on Builder was released on September 26, 2023.

  • Fixed the security issues where AOB was logging the session_key and password in plain text during the input creation process.
  • Fixed the issue where user was not able to rename the already configured TA.

Version 4.1.3

Version 4.1.3 of the Splunk Add-on Builder was released on April 28, 2023.

Fixed the issue where default values were not being set in the settings.conf file for additional_parameters stanza for the TAs built using AOB.

Version 4.1.2

Version 4.1.2 of the Splunk Add-on Builder was released on February 14, 2023.

Fixed a security vulnerability where the rest API inputs created by the add-on builder allowed connection to insecure URLs.

Security Vulnerability observed in Splunk Add-on Builder v4.1.1

While creating a REST API input using a self signed URL, the Add-on builder successfully makes a connection request with the insecure URL and will make a successful connection with any insecure URLs that do not have the correct certificates. This vulnerability is resolved in Splunk Add-on Builder v4.1.2.

For upgrade steps, see Upgrade from version 4.1.1 or lower to version 4.1.2 of the Splunk Add-on Builder.

Version 4.1.1

Version 4.1.0

  • Upgraded vulnerable dependencies and fixed security issues.
  • Fixed package validation issue on Windows.

To update to 4.0.1:

Upgrade add-ons from earlier versions

When you open an add-on project that was created in an earlier version of Add-on Builder, the add-on is automatically upgraded. Note the following changes:

  • Any UI or dashboards that were created outside of Add-on Builder will no longer be available.
  • If you made any changes outside of Add-on Builder to configuration files, review these files in case your changes were not migrated.
  • Setup pages have changed in version 2.1.0 and are upgraded to the new style. Due to changes between these styles, review your setup pages and verify the text appears correctly. Ensure that display labels for input fields are unique.
  • If you created data inputs with Python code in Add-on Builder 2.0.0, you must upgrade your code for version 2.1.0.

  • The framework for modular inputs has changed. See below for details about migrating your code.
  • Bug fixes. For details, see Fixed issues.

Migrating modular input code from an earlier release

The framework for modular inputs has changed. If you are upgrading the Add-on Builder app from a previous release, update your Python code for any modular inputs you created as described below.

Create events

Use the self.new_event method to create events for modular inputs rather than creating an event directly using smi.Event. The arguments are the same.

For example, in the auto-generated code for modular inputs, you would update the sample code as follows.

1. Find this line: 

event = smi.Event(source=self.input_name, index=self.output_index, sourcetype=self.output_sourcetype, data=data)

2. Replace it with this line: 

event = self.new_event(source=self.get_input_name(), index=self.get_output_index(), sourcetype=self.get_sourcetype(), data=data)

Read configurations from setup pages

The following example code, also included in the auto-generated code for modular inputs, shows how to read configurations from setup pages in the new framework for version 1.1.0: 

arg_value = self.get_arg('arg_name')
proxy_settings = self.get_proxy()
account = self.get_user_credential("admin")
userdefined = self.get_global_setting("userdefined")

Version 1.0.1
