The Quick Page/Post Redirect Plugin for WordPress is vulnerable to authorization bypass due to missing capability checks on the qppr_save_quick_redirect_ajax and qppr_delete_quick_redirect functions in versions up to, and including, 5.1.9. This makes it possible for low-privileged attackers to interact with the plugin settings and to create a redirect link that would forward all traffic to an external malicious website.

Cross-site request forgery (CSRF) vulnerability in the Quick Page/Post Redirect plugin before 5.0.5 for WordPress allows remote attackers to hijack the authentication of administrators for requests that conduct cross-site scripting (XSS) attacks via the quickppr_redirects[request][] parameter in the redirect-updates page to wp-admin/admin.php.
