Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The Packagist package laravel/framework is affected in versions below 10.48.29, from 11.0.0 up to but not including 11.44.1, and from 12.0.0 up to but not including 12.1.1. When wildcard validation is used on a file or image field array (files.*), a specially crafted request may be able to bypass the validation rules. The source gives few details about the exact conditions or impact. Upgrade to 10.48.29, 11.44.1, or 12.1.1, depending on the major version in use.
