    "summary": "Provides the Bootstrap front-end framework as a Drupal theme. Bootstrap theme did not sufficiently filter certain attributes, which could lead to a cross-site scripting vulnerability. This vulnerability is mitigated by only affecting the optional tooltip and popover features. A short-term mitigation is to disable tooltips and popovers on `admin/appearance/settings/bootstrap` or `admin/appearance/settings/my_bootstrap_subtheme`.",
