During a security review of the simple embed code plugin for the hacks blog (bug 771050), I found an XSS vulnerability in the "search" admin page. This is executed using a link such as:
Although behind the login page, this link could be sent to a blog author or clicked on by one causing the code to execute.
I've contacted the developer of this plugin.
This blocks the installation of the plugin.
The developer has replied and updated the plugin to version 2.0.2 which fixes the XSS issue. I am marking this bug resolved.
The plugin has been updated and is live in the WordPress.org repository - version 2.0.2.
Let me know if there are any issues and, naturally, if there's any further functionality that your developers would like to see it cover please feel free to contact me.
