description

Mang Board for WordPress through version 2.4.0 improperly handles a request parameter, allowing unauthenticated parties to save browser-executed content. That content can run when a user visits an affected page.

mitigation

Disable and remove Mang Board from internet-accessible WordPress sites until the maintainer publishes a corrected release. If it must remain installed, restrict public access to plugin functionality where feasible and inspect existing content for injected markup.
