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.

Severity, decoded
CVSS 4.0Exploitable over the network under specific conditions, with no privileges and no user interaction, leading to full loss of confidentiality, integrity and availability.
How the score is built
- Attack vectorAn attacker can reach it over the internet; no access to your network needed.Network
- Attack complexityThe attacker must first defeat a security measure, such as address randomisation, or obtain a secret.High
- Attack requirementsThe attack works without any special deployment or timing conditions.None
- Privileges requiredNo account or login is needed.None
- User interactionNo one has to click or open anything; the attack works on its own.None
- Confidentiality impact (vulnerable system)An attacker can read all data the affected component holds, or the most sensitive parts of it.High
- Integrity impact (vulnerable system)An attacker can change any data or files the affected component protects.High
- Availability impact (vulnerable system)An attacker can take the component down completely or keep it from serving anyone.High
- Confidentiality impact (other systems)Other systems' data is not exposed.None
- Integrity impact (other systems)Other systems' data cannot be changed.None
- Availability impact (other systems)Other systems keep working normally.None
CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:NAttackers are exploiting this in the wild.
At least one step needs hands-on work, which slows mass attacks.
A successful attack gives full control over the affected software or all of its data.

Vendor statements
QuotedCloudflareWAF Managed Rules
We found no public statement from this vendor naming this CVE. That is not proof of no protection: generic rules may still catch it. Each row gives the rule ID and its default action. The feed starts in January 2025, so older rules are missing.
AWSAWS WAF Managed Rules
We found no public statement from this vendor naming this CVE. That is not proof of no protection: generic rules may still catch it. AWS often describes a vulnerability without naming its CVE (for example "Log4j"). We count only entries that name the CVE, so AWS coverage is understated.
Microsoft AzureFront Door and Application Gateway WAF (DRS)
We found no public statement from this vendor naming this CVE. That is not proof of no protection: generic rules may still catch it. The rule tables name CVEs but carry no dates, so Azure is left out of every time-to-rule figure.
Google CloudCloud Armor preconfigured WAF rules
We found no public statement from this vendor naming this CVE. That is not proof of no protection: generic rules may still catch it. Google names few CVEs: the release notes start in May 2024 and the rules reference lists CVEs without dates. Its cve-canary rules are opt-in.
FastlyNext-Gen WAF virtual patches
The CVE predates the oldest entry in this vendor's public feed, so a rule may exist that we cannot see.
F5Attack signatures (Distributed Cloud WAF)
First rule 2026-07-07, 355 days after the CVE was published.
Added: signature 200204072 "Livewire Unauthenticated Remote Code Execution" (Server Side Code Injection, risk High), systems: PHP. References: CVE-2025-54068.
AkamaiApp & API Protector (Adaptive Security Engine)
This vendor publishes no machine-readable rule changelog we can check.
OWASP CRSCore Rule Set (open source, used inside many WAFs)
We found no public statement from this vendor naming this CVE. That is not proof of no protection: generic rules may still catch it. CRS rarely names CVEs: it relies on generic detections. Our own lab measures what it actually blocks.
