Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
Laravel is a web application framework. Versions of Laravel before 6.20.11, 7.30.2 and 8.22.1 contain a query binding exploitation. This same exploit applies to the illuminate/database package which is used by Laravel. If a request is crafted where a field that is normally a non-array value is an array, and that input is not validated or cast to its expected type before being passed to the query builder, an unexpected number of query bindings can be added to the query. In some situations, this will simply lead to no results being returned by the query builder; however, it is possible certain queries could be affected in a way that causes the query to return unexpected results.

Session Fixation

Close remember_me Timing Attack Vector
This package mishandles the `remember_me token` verification process because `DatabaseUserProvider` does not have constant-time token comparison.

Unexpected database bindings
This is a follow-up to the previous security advisory (GHSA-3p32-j457-pg5x) which addresses a few additional edge cases.

If a request is crafted where a field that is normally a non-array value is an array, and that input is not validated or cast to its expected type before being passed to the query builder, an unexpected number of query bindings can be added to the query. In some situations, this will simply lead to no results being returned by the query builder; however, it is possible certain queries could be affected in a way that causes the query to return unexpected results.

Unsafe payload decryption
There's a potential exploit of the Laravel Encrypter component that may cause the Encrypter to fail on decryption and unexpectedly return false. To exploit this, the attacker must be able to modify the encrypted payload before it is decrypted. This could lead to unexpected behavior when combined with weak type comparisons.

SQL Server LIMIT / OFFSET SQL Injection in laravel/framework and illuminate/database
### Impact

Those using SQL Server with Laravel and allowing user input to be passed directly to the `limit` and `offset` functions is vulnerable to SQL injection. Other database drivers such as MySQL and Postgres are not affected by this vulnerability.

### Patches

This problem has been patched on Laravel versions 6.20.26, 7.30.5, and 8.40.0.

### Workarounds

You may workaround this vulnerability by ensuring that only integers are passed to the `limit` and `offset` functions, as well as the `skip` and `take` functions.
