A critical security vulnerability in Laravel’s Livewire framework has been discovered that could expose millions of web applications to remote code execution (RCE) attacks.

The flaw, designated as CVE-2025-54068, affects Livewire v3 versions from 3.0.0-beta.1 through 3.6.3, with a CVSS v4 score indicating high severity across confidentiality, integrity, and availability metrics.

The vulnerability originates from improper handling of component property updates during hydration processes and requires no authentication or user interaction for exploitation.

Key Takeaways
1. Livewire v3 RCE flaw allows unauthenticated remote attacks (CVE-2025-54068).
2. Versions 3.0.0-beta.1 to 3.6.3 affected.
3. Upgrade to v3.6.4 immediately - no workaround available.

Livewire v3 Remote Code Execution Vulnerability

The security flaw resides specifically in Livewire v3’s property update hydration mechanism, which processes component state changes on the server side.

Unlike previous versions of the framework, this vulnerability is unique to v3 and allows unauthenticated attackers to achieve remote command execution through network-based attacks.

The attack complexity is rated as high, meaning exploitation requires specific component configurations, but critically, no privileges or user interaction are necessary for successful attacks.

The vulnerability’s attack vector classification as “Network” with “Attack Requirements: None” indicates that malicious actors can potentially exploit vulnerable applications remotely without requiring local access or special conditions.

This makes the vulnerability particularly dangerous for internet-facing Laravel applications utilizing affected Livewire versions.

Security researchers have classified this vulnerability as critical, with the CVSS v4 base metrics showing maximum impact scores for confidentiality, integrity, and availability of vulnerable systems.

The vulnerability affects all Livewire installations running versions 3.0.0-beta.1 through 3.6.3, potentially impacting thousands of Laravel applications worldwide that have adopted the newer v3 framework.

The exploitation scenario requires components to be “mounted and configured in a particular way,” suggesting that while not all Livewire v3 installations may be vulnerable, those meeting the specific conditions face immediate risk of complete system compromise.

The high availability impact score indicates that successful exploitation could result in system disruption or denial of service conditions.

Risk Factors	Details
Affected Products	Livewire/Livewire (Composer package)Versions: 3.0.0-beta.1 through 3.6.3
Impact	Remote Code Execution (RCE)
Exploit Prerequisites	– Component must be mounted and configured in specific way- No authentication required- No user interaction needed- Network-based attack vector- High attack complexity
CVSS Score	9.2 (Critical)

Mitigations

Livewire has released version 3.6.4 to address this critical vulnerability, with all users strongly encouraged to upgrade immediately.

Currently, no workaround exists for this security flaw, making the patch update the only viable mitigation strategy.

The development team has indicated that detailed technical information will be published following a responsible disclosure window to prevent widespread exploitation of unpatched systems.

Organizations running affected Livewire versions should prioritize this update as part of their emergency patch management procedures, given the vulnerability’s potential for unauthenticated remote code execution and its critical CVSS rating.
