### Impact

Sequelize 6.28.2 and prior has a dangerous feature where using parentheses in the attribute option would make Sequelize use the string as-is in the SQL

```ts User.findAll({ attributes: [ ['count(id)', 'count'] ] }); ```

Produced

```sql SELECT count(id) AS "count" FROM "users" ```

### Patches

This feature was deprecated in Sequelize 5, and using it prints a deprecation warning.

This issue has been patched in [`@sequelize/core@7.0.0.alpha-20`](https://github.com/sequelize/sequelize/pull/15374) and [`sequelize@6.29.0`](https://github.com/sequelize/sequelize/pull/15710).

In Sequelize 7, it now produces the following:

```sql SELECT "count(id)" AS "count" FROM "users" ```

In Sequelize 6, it throws an error explaining that we had to introduce a breaking change, and requires the user to explicitly opt-in to either the Sequelize 7 behavior (always escape) or the Sequelize 5 behavior (inline attributes that include `()` without escaping). See https://github.com/sequelize/sequelize/pull/15710 for more information.

### Mitigations

Do not use user-provided content to build your list or attributes. If you do, make sure that attribute in question actually exists on your model by checking that it exists in the `rawAttributes` property of your model first.
