Name of the Vulnerable Software and Affected Versions User Registration WordPress plugin versions prior to 3.0.4.2

Description The issue allows high-privilege users, such as admins, to perform Stored Cross-Site Scripting attacks. This is possible because the plugin does not properly sanitize and escape some of its settings, even when the unfiltered html capability is disallowed, for example, in a multisite setup.

Recommendations For versions prior to 3.0.4.2, update to version 3.0.4.2 or later to resolve the issue. As a temporary workaround, consider restricting the ability of high-privilege users to modify plugin settings until the update is applied.
