No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The BJ Lazy Load plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the filter_images() function in all versions up to, and including, 1.0.9. This is due to the use of regex-based HTML processing (preg_replace) that does not properly handle HTML attribute boundaries when replacing src attributes, allowing crafted content inside a class attribute value to be promoted to real DOM attributes after processing. 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.
