CRITICAL 9.8

DescriptionGitHub Advisory

Livewire is a full-stack framework for Laravel. In Livewire v3 up to and including v3.6.3, a vulnerability allows unauthenticated attackers to achieve remote command execution in specific scenarios. The issue stems from how certain component property updates are hydrated. This vulnerability is unique to Livewire v3 and does not affect prior major versions. Exploitation requires a component to be mounted and configured in a particular way, but does not require authentication or user interaction. This issue has been patched in Livewire v3.6.4. All users are strongly encouraged to upgrade to this version or later as soon as possible. No known workarounds are available.

AnalysisAI

Laravel Livewire v3 through v3.6.3 contains a critical remote code execution vulnerability (CVE-2025-54068, CVSS 9.8) that allows unauthenticated attackers to execute commands through improper hydration of component property updates. KEV-listed with EPSS 16%, this vulnerability affects one of the most popular PHP frameworks, potentially compromising thousands of Laravel applications using Livewire for reactive server-side rendering.

Technical ContextAI

Livewire is a full-stack framework for Laravel that enables reactive server-side rendering. Component state is serialized, sent to the client, and deserialized (hydrated) on subsequent requests. The vulnerability exists in how certain property updates are hydrated — attacker-controlled data can influence the hydration process to execute arbitrary PHP code. This affects Livewire v3 specifically (introduced in the v3 rewrite) and is exploitable without authentication on any page using vulnerable component patterns.

RemediationAI

Upgrade Livewire to v3.6.4 or later immediately. If unable to upgrade, review component property definitions for potentially vulnerable patterns. Rotate all secrets in .env after patching. Audit application logs for suspicious Livewire requests.
