GRANT OPTION allows to see databases

    XMLWordPrintable

    Details

      Description

      to see a database, for example, in SHOW DATABASES a user must have at least some privilege on that database. GRANT OPTION is enough:

      GRANT USAGE ON *.* TO user@host WITH GRANT OPTION;
      

      allows to see all databases.

      As GRANT OPTION is not a real privilege, perhaps it shouldn't allow to see databases?

      MySQL Bug#25203933, fixed in 5.7.40 and in 8.0.17
