Short explanation
The plugin allows authentication bypass by using a predictable email‑verification token via the `cusomer_email_verify` parameter. An attacker can log in as an existing user or a newly created account tied to any email address. Exploitation requires the `cev_user_log` table to contain a `password` column, which is absent in fresh 2.8.2 installations but present on sites upgraded from older versions.
An attacker can gain access to a store customer account without any credentials, increasing the risk of unauthorized purchases and data leakage.
What should be done?
- Monitor vendor advisory and upgrade when a fixed version is released
- Implement strong random token generation and proper nonce verification
- Secure or remove the `password` column in the `cev_user_log` table
- Use WordPress security plugins for monitoring and anomaly detection
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.

Show the technical text from the sources
The Customer Email Verification for WooCommerce plugin for WordPress is vulnerable to Authentication Bypass via a Predictable Email-Verification Token in all versions up to, and including, 2.8.2. This is due to the `authenticate_user_by_email_link()` function — hooked on the `wp` action and triggered by the `cusomer_email_verify` GET parameter — lacking any capability check or nonce verification, while the `secret_code` it validates is generated as `md5(email . time())` and the `verify_otp_nonce` required to trigger token issuance via the `wp_ajax_nopriv_resend_otp` handler is emitted to every front-end visitor through `wp_localize_script`. This makes it possible for unauthenticated attackers to log in as a newly created, verified WooCommerce customer bound to an arbitrary email address — or to flip an existing account's `customer_email_verified` meta to verified — fully bypassing the plugin's core email-verification control. Exploitation requires the `cev_user_log` table to contain a `password` column, which is absent from the fresh-install schema shipped in version 2.8.2 but is present on sites upgraded from an older version where that column was defined.
