A flaw in older versions of this library means that, under specific conditions, that filter can be bypassed, allowing harmful scripts to slip through and run in your visitors' browsers. The fix is a straightforward library update.

Bootstrap 3 is also no longer maintained, so no official fix will be released for this version.
