CVE-2024-3243Network attack vector

Subscriber-level arbitrary email sending via missing capability check

Published Apr 16, 2024 · Updated Apr 8, 2026

Missing authorization in CusRev Customer Reviews for WooCommerce 5.46.0 and earlier allows remote authenticated users to send arbitrary test emails. The send_test_email() function performs its email-sending action without verifying that the requesting account has the required capability. Subscriber-level WordPress access is sufficient, and the bounded consequence is unauthorized outbound email rather than code execution or data disclosure.
