Recommendation: Plan a near-term fix — a public PoC already exists.

The WP Responsive Images plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.0 via the 'src' parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information.
