CVE-2026-1000
The MailerLite - WooCommerce integration plugin for WordPress is vulnerable to unauthorized data modification and deletion in all versions up to, and including, 3.1.3.
Does this matter?
Lower severity and a low EPSS score (0.32%). Track it; it rarely justifies an emergency change on its own.
Description
The MailerLite - WooCommerce integration plugin for WordPress is vulnerable to unauthorized data modification and deletion in all versions up to, and including, 3.1.3. This is due to missing capability checks on the resetIntegration() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to reset the plugin's integration settings, delete all plugin options, and drop the plugin's database tables (woo_mailerlite_carts and woo_mailerlite_jobs), resulting in complete loss of plugin data including customer abandoned cart information and sync job history.
