EPSS

• CVE-2025-54068: 96.28% estimated exploitation activity in the next 30 days; percentile 99.88 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact In Livewire v3 (≤ 3.6.3), 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. Patches 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. Workarounds There is no known workaround at this time. Users are strongly advised to upgrade to a patched version immediately. Resources No public references available at this time to avoid exposure. Details will be published after a responsible disclosure window.

# Patch Next advisory brief: CVE-2025-54068

Advisory: Livewire is vulnerable to remote command execution during component property update hydration
IDs: CVE-2025-54068, GHSA-29cq-5w36-x7w3
Record: https://patchnext.com/advisories/cve-2025-54068 (revision 1, source checked 26 Oct 2026, 14:38 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.2)
Exploitation: confirmed: listed in the CISA Known Exploited Vulnerabilities catalog.
Vendor response: Vendor fix available; fixed versions by package: livewire/livewire 3.6.4. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist livewire/livewire: affected >= 3.0.0-beta.1, < 3.6.4; fixed in 3.6.4

## Suggested inspection (read-only)
- Packagist livewire/livewire: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on livewire/livewire.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Mark the work resolved only after the fixed version is verified in production.
