Security breach regarding Permission schemes when a JQL iteration is defined on templates

Through JQL expression, it is possible to export all information in jira, bypassing the security that may exist (using permission schemes).

Steps to reproduce:

1. Disable Xporter for all users and projects
2. Create a project called "DEMO"
3. Create a permission scheme to allow export Stories from DEMO project.
4. Create a template with a JQL iteration where the JQL query return issues from another project, for example
5. Install the template
6. Go to a DEMO Story issue and export using the template created.
