Duplicator < 5.1.0 - Subscriber+ SQLi via Charset and Collation Rewriter During Restore

The Duplicator WordPress plugin before 5.1.0, duplicator-pro WordPress plugin before 5.1.0 does not restrict its database charset and collation rewrite to schema statements during a restore, so a value a Subscriber stores in their own profile can break out of its string literal and inject SQL into the restore's INSERT statement when an administrator restores the backup onto a server lacking one of the source's charsets or collations.
