icingaweb2-module-jira provides integration with Atlassian Jira. Starting in version 1.3.0 and prior to version 1.3.2, template and field configuration forms perform the deletion action before user input is validated, including the cross site request forgery token. This issue is fixed in version 1.3.2. There are no known workarounds.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
