Precise Columns <= 1.0 - Authenticated (Contributor+) Stored Cross-Site Scripting

The Precise Columns plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `wrap_id` shortcode attribute in all versions up to, and including, 1.0. This is due to the plugin not properly sanitizing user input or escaping output when inserting the wrapper ID into the generated HTML. 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.
