Is SingleStoreDB vulnerable to MySQL server security issues?

No. The SingleStoreDB and MySQL servers are separate database engines which do not share any code, so security issues in the MySQL server are not applicable to SingleStoreDB.

SingleStoreDB implements the MySQL wire protocol in order to provide compatibility with MySQL client software. A part of this compatibility involves reporting a MySQL version number as described above. As a result of this, numerous third-party security scanners that use the reported version number as a vulnerability marker report false positives, as they’re looking at a version number, not at the actual presence of a vulnerability. Our engineering team as well as a third-party security analysis have confirmed that SingleStoreDB is not susceptible to these MySQL vulnerabilities.
