## What to check

- Applies to: Not tied to a specific actor, malware or CVE, only to the sectors it covers, so it may be general reporting. Check the source before acting on it. Whether it concerns you is not assessed.

CERT-FR issued an advisory regarding a vulnerability discovered in the Laravel PHP framework that could allow an attacker to achieve arbitrary remote code execution. The affected systems are all Laravel installations running versions prior to 13.40.0. The advisory references a security bulletin published by Laravel on GitHub Security Advisories (GHSA-63hm-g96r-2m2q) dated 04 November 2026.

No technical details on the exploitation mechanism are provided in this advisory, nor is there any indication of active exploitation in the wild. CERT-FR's recommendation is straightforward: administrators should consult the vendor's security bulletin and apply the available patches to update to Laravel 13.40.0 or later. Given Laravel's widespread use as a PHP web application framework, organizations running affected versions should prioritize patching to mitigate potential remote code execution risk.
