  "details": "An incorrect visibility condition in the MISP event template builder allowed authenticated non-site-admin users to view galaxies that should not have been visible to their organisation. The custom access-control condition intended to restrict galaxies to those owned by the user’s organisation or distributed beyond it used a PHP comparison expression instead of a query condition. As a result, enabled galaxies, including organisation-only custom galaxies belonging to other organisations, could be exposed in the template builder galaxy list. This could disclose metadata about private galaxy definitions to unauthorised users.",
