Resolved When use H2/MySQL/TiDB as Apache SkyWalking storage, the metadata query through GraphQL protocol, there is a SQL injection vulnerability, which allows to access unpexcted data. Apache SkyWalking 6.0.0 to 6.6.0, 7.0.0 H2/MySQL/TiDB storage implementations don't use the appropriate way to set SQL parameters.
