Upgrade the Membership Plugin WordPress plugin to version 4.0.6 or later, where authorization and CSRF checks have been implemented to prevent unauthorized execution of the database maintenance routine. Until upgraded, restrict access to the affected functionality to trusted users only.
Description
The Membership Plugin WordPress plugin versions before 4.0.6 lack authorization and CSRF protections on a database maintenance routine. This flaw allows unauthenticated users to alter the plugin's database tables by converting them to a narrower character set, which irreversibly replaces all 4-byte characters such as emoji and certain CJK characters with question marks in membership level, discount code, and payment records.
