Description
The Blacklist Manager for WooCommerce WordPress plugin from 1.3.0 to 2.3.1 does not enforce its user blocking on every authentication path, allowing the holder of an account the site owner has blocked to keep authenticating with that account's privileges, without the block being enforced or recorded.
