An issue was discovered in Laravel before 6.18.35 and 7.x before 7.24.0. The $guarded property is mishandled in some situations involving requests with JSON column nesting expressions.

An issue was discovered in Laravel before 6.18.34 and 7.x before 7.23.2. Unvalidated values are saved to the database component in some situations in which table names are stripped during a mass assignment.

Description

Laravel versions <6.20.12, <7.30.3 & <8.22.1 contain a query binding exploitation.

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.

This vulnerability was discovered by Tim Groenevelt (tim.g@foodbyus.com).
