Updated 3pm: We’ve proactively blocked access from the internet to exposed servers and related ports for a small group of schools as a precautionary measure.

We’re reaching out to the impacted schools with more information.

Please note that schools should still follow the guidance outlined below for other relevant services and systems.

10am: We’re aware of two critical vulnerabilities in PHP impacting websites and other online services from a number of providers (CVE-2026-109618, CVE-2026-109619).

If exploited, these vulnerabilities could allow unauthenticated remote code execution (RCE) on impacted web services.

We’re currently reviewing the issue and potential mitigations for N4L-managed services.

  • What schools need to do
    Check with your vendors: if any of your school web services (for example, WordPress) or on-premise systems use PHP, we strongly recommend you check with the software provider and your IT contact to ensure they’re aware of the issue and are taking appropriate action.
  • Upgrade school-managed systems: we strongly recommend you upgrade any school-managed services using PHP as per guidance from the National Cyber Security Centre here.
