Snipe-IT is an IT asset/license management system. Prior to 8.7.0, a user with the customfields.create permission can store markup in CustomField.name, and app/Presenters/AssetPresenter.php assigns that value as an unescaped bootstrap-table header title. When another user opens an asset-list page associated with the fieldset, the stored markup executes on page load in that user's Snipe-IT session.
This can expose same-origin data and perform authenticated actions with the victim's privileges, including privilege escalation when a superuser views the affected list. This issue is fixed in version 8.7.0.
