*Security note*: Make sure that the database connection uses credentials
|
|
|
|
|
that are narrowly-scoped to only include necessary permissions.
|
|
|
|
|
Failure to do so may result in data corruption or loss, since the calling
|
|
|
|
|
code may attempt commands that would result in deletion, mutation
|
|
|
|
|
of data if appropriately prompted or reading sensitive data if such
|
|
|
|
|
data is present in the database.
|
|
|
|
|
The best way to guard against such negative outcomes is to (as appropriate)
|
|
|
|
|
limit the permissions granted to the credentials used with this tool.
