ShortcodeHub <= 1.7.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via author_link_target Parameter

The ShortcodeHub plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘author_link_target’ parameter in all versions up to, and including, 1.7.1 due to insufficient input sanitization and output escaping. 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.
