Description
This module enables you to add a variety of meta tags to a site for helping with a site’s search engine results and to customize how content is shared on social networks.
The module doesn’t sufficiently protect against data being cached that might contain information related to a specific user.
This vulnerability is mitigated by the fact that a site must have a page with sensitive data in the page title that varies per logged in user.
