Thousands of companies filters, dashboards and staff data were publically exposed. It occurs because of the wrong permissions scheme set to filters and dashboards hence providing their access even to non-logged in users and hence leading to leaking of sensitive data. […] Some of the companies were from Alexa and Fortune top list including big giants like NASA, Google, Yahoo, etc and government sites as well.
This is not a misconfiguration, though, it’s extremely poor UI/UX by JIRA. Creating a filter gives you the option to share it with “Everyone”, which sounds like “Everyone in the Company”, but means “public”. “Everyone in the company” is actually called “Open” - and not even part of the Share Filter UI.
