Livewire Filemanager Vulnerability Exposes Web Apps to Remote Code Execution

A critical vulnerability in Livewire Filemanager, a widely-used file management component for Laravel applications, has been disclosed by the CERT Coordination Center.

Tracked as CVE-2025-14894 and assigned CERT vulnerability note VU#650657, this flaw enables unauthenticated remote code execution (RCE) on affected systems.

The vulnerability stems from insufficient file validation mechanisms that permit attackers to upload and execute malicious PHP files within web-accessible directories.

Technical Analysis

Livewire Filemanager is embedded within Laravel, a popular PHP web application framework, to handle file uploads and storage management.

The vulnerability exists because the component lacks proper file type and MIME validation during the upload process.

This design gap allows an attacker to bypass restrictions and upload a malicious PHP file directly to the application server.

When the PHP artisan storage: link command is executed, a standard Laravel setup procedure uploads files that become accessible via the publicly exposed “storage/app/public” URL path.

An attacker exploiting this vulnerability can craft a request to the web-accessible directory, passing a user ID parameter alongside the malicious PHP file.

Upon execution, the uploaded file runs with the privileges of the web server user, granting full read and write access to all files within that user’s scope.

This capability extends beyond simple file manipulation; attackers can establish reverse shells, inject backdoors, or pivot laterally to compromise connected infrastructure.

CVE-2025-14894 represents a severe risk to Laravel-based web applications.

The vulnerability requires no authentication, meaning any unauthenticated attacker with network access can execute arbitrary code remotely.

Organizations running Livewire Filemanager should immediately assess their exposure, particularly those with internet-facing Laravel applications.

The ability to execute code with web server privileges can lead to cascading compromises, enabling attackers to exfiltrate sensitive data, deploy ransomware, or use compromised servers as staging points for further attacks.

Vulnerability Details
CVE ID	CVE-2025-14894
CERT ID	VU#650657
Component	Livewire Filemanager (LivewireFilemanagerComponent.php)
Affected Framework	Laravel PHP Framework
Vulnerability Type	Insecure File Upload leading to RCE
Authentication Required	No
CVSS Score	High
Disclosure Date	January 16, 2026
Vendor Status	No acknowledgment at time of publication

CERT/CC advises immediate caution regarding Livewire Filemanager deployments. Organizations should verify whether the PHP artisan storage: link command has been executed on their servers.

If confirmed, administrators should disable the public web serving capability of the storage directory to prevent direct file access.

Additionally, implement strict file type validation at the application level, independent of Livewire Filemanager’s built-in mechanisms, to reject non-whitelisted file extensions.

Organizations should also consider monitoring upload directories for suspicious PHP files and implementing web application firewalls with rules targeting file upload exploitation patterns.

As the vendor has not yet acknowledged CVE-2025-14894, users should monitor official Laravel and Livewire security channels for patches.

Until a patch is released, deploying additional authentication layers around file management functionality or temporarily disabling file upload capabilities may be necessary for high-risk environments.
