Description

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.
