A significant security flaw, CVE-2024-52301, has been found in the Laravel framework, which is widely used for web applications. With a CVSS rating of 8.7, this vulnerability could allow unauthorized access, data tampering, and privilege escalation in many Laravel applications.
CVE-2024-52301 pertains to inadequate input validation in Laravel’s environment configuration. The problem arises from how Laravel manages PHP’s register_argc_argv directive, which allows command-line arguments in scripts. If this directive is enabled, attackers could exploit it with malicious URLs to modify environment variables used by Laravel during request processing.

Improper validation allows attackers to bypass input checks or inject harmful data. With register_argc_argv enabled, Laravel applications are at higher risk, as attackers can exploit PHP’s default behavior to gain unauthorized control over the application.
Laravel is popular for web applications and APIs, making its vulnerability a significant concern due to its widespread use. This flaw impacts several versions of Laravel, including:
Versions < 6.20.45
Versions >= 7.0.0 and < 7.30.7
Versions >= 8.0.0 and < 8.83.28
Versions >= 9.0.0 and < 9.52.17
Versions >= 10.0.0 and < 10.48.23
Versions >= 11.0.0 and < 11.31.0
Organizations using these Laravel versions for public applications may be vulnerable to attacks that could lead to unauthorized access and data breaches.
In response to CVE-2024-52301, Laravel has issued patches across affected versions, with the updated versions being:
6.20.45
7.30.7
8.83.28
9.52.17
10.48.23
11.31.0
The latest Laravel patch prevents environment detection using argv values on non-CLI interfaces, closing a security vulnerability. Developers should upgrade to the updated versions immediately.
