Unauthenticated remote code execution in Ignition

Published Jan 12, 2021 · Updated Oct 21, 2025 · Assigned by mitre

Package: facade/ignition Ecosystem: Packagist

Description

Ignition before 2.5.2, as used in Laravel and other products, allows unauthenticated remote attackers to execute arbitrary code because of insecure usage of file_get_contents() and file_put_contents(). This is exploitable on sites using debug mode with Laravel before 8.4.2.
