Easy Author Image <= 1.7 - Authenticated (Subscriber+) Stored Cross-Site Scripting via Profile Picture URL

The Easy Author Image plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'author_profile_picture_url' parameter in all versions up to, and including, 1.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
