Upgrade the Membership Plugin to version 4.0.6 or later, where this vulnerability is fixed. Until then, restrict access to the plugin's maintenance routines and consider additional protective measures such as web application firewalls to block unauthorized requests. No other vendor advisories indicate alternate mitigations or that no action is required.
Description
A missing authorization and CSRF check vulnerability exists in the Membership Plugin WordPress plugin before version 4.0.6. This flaw allows unauthenticated users to trigger a schema-altering database maintenance routine that converts the plugin's tables to a narrower character set. This conversion irreversibly replaces every 4-byte character, including emoji and some CJK characters, in membership level, discount code, and payment records with question marks.
