Description
The Image Source Control Lite – Show Image Credits and Captions plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Image Source' attachment field in all versions up to, and including, 3.9.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
