Overview
Laravel framework disclosed a security vulnerability (CVE-2025-27515) on March 5, 2025, affecting its file validation functionality. The vulnerability exists in the framework's wildcard validation mechanism when validating file or image field arrays.

Technical details
The vulnerability stems from a flaw in Laravel's wildcard validation mechanism when handling file or image field arrays using the files.* pattern.

Impact
When exploited, this vulnerability could allow attackers to bypass file validation rules, potentially leading to unauthorized file uploads or processing of files that should have been rejected by the validation rules. This could impact the security of applications relying on Laravel's file validation mechanism (GitHub Advisory).
