The WP-Eggdrop plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 0.1. This is due to missing or incorrect nonce validation on the wpegg_updateOptions() function. This makes it possible for unauthenticated attackers to update the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The WP-Eggdrop plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 0.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
