Cross-site request forgery (CSRF) vulnerability in the WP Limit Posts Automatically plugin 0.7 and earlier for WordPress allows remote attackers to hijack the authentication of administrators for requests that conduct cross-site scripting (XSS) attacks via the lpa_post_letters parameter in the wp-limit-posts-automatically.php page to wp-admin/options-general.php.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
