The Simple:Press Forum WordPress plugin before 6.10.11 does not sanitise and escape a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting.

The Simple:Press Forum plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 's' parameter in all versions up to, and including, 6.10.11 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The Simple:Press Forum plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.10.12. This is due to missing or incorrect nonce validation on the 'sp_save_edited_post' function. This makes it possible for unauthenticated attackers to modify a forum post via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
