Cross-site request forgery in MailerLite – WooCommerce integration 2.0.8 and earlier allows remote attackers to trigger unauthorized actions. Multiple AJAX handlers omit or incorrectly perform nonce validation, so forged requests execute in an authenticated administrator's session. Exploitation requires an administrator to click a malicious link or take an equivalent action; the affected administrative operations are undisclosed.
