Description
The Smart Post plugin for WordPress is vulnerable to Sensitive Information Exposure via the [smart_post] saved template shortcode in all versions from 4.0.0 up to, and including, 4.0.8. This is due to the shortcode rendering the post_content of any published post ID without checking that the post is a saved template (sp_post_template) or that it is not password protected. This makes it possible for authenticated attackers, with Contributor-level access and above, to view the content of password-protected posts and of published entries of other post types when the Saved Templates module is enabled.
