Summary

This was nice little bug which was more like bypassing client side access control than privilege escalation but bug itself allowed to use more privileged functionalities without paying.

How it was found

Hello team!

I've found a privilege escalation issue which allows to set iframes to the projects w/o upgrading.

Steps to reproduce

  • Login
  • Navigate to the project
  • Choose integrations and click the IFrame
  • See that you'll get upgrade now notification {F501019}
  • Inspect the page with developer tool and choose the upgrade from IFrame icon
  • Delete the data-upgrade="true" part {F501023}
  • Click the IFrame and see that you are able to add iframe to the page w/o upgrade {F501024}

If you need any information please let me know.

Cheers!
