Description

The Bold Timeline Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `supertitle` and `subtitle` attributes of the `bold_timeline_item` shortcode in all versions up to, and including, 1.2.8 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
