DESCRIPTION
Avo is a framework to create admin panels for Ruby on Rails apps.
In Avo 3 pre12 any HTML inside text that is passed to error or
succeed in an Avo::BaseAction subclass will be rendered directly
without sanitization in the toast/notification that appears in the
UI on Action completion. A malicious user could exploit this
vulnerability to trigger a cross site scripting attack on an
unsuspecting user.
This issue has been addressed in the 3.0.2 release of Avo. Users are advised to upgrade.
