LinkedIn SC <= 1.1.9 - Authenticated (Administrator+) Stored Cross-Site Scripting via Settings Page

The LinkedIn SC plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'linkedin_sc_date_format', 'linkedin_sc_api_key', and 'linkedin_sc_secret_key' parameters in all versions up to, and including, 1.1.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the injected page.
