Important Security Update: PHP Security Mitigations

Update timeline

1. identified Oct 21, 2026, 01:49 PM UTC

   Dear Customer, We’d like to share an update regarding two recently identified critical PHP security vulnerabilities, CVE-2026-109618 and CVE-2026-109619. Protecting our customers’ websites and data is a priority. As a precaution, our security and infrastructure teams applied temporary security mitigations across our shared hosting servers on 21 October 2026 while the permanent fixes are being prepared. How might this affect your website? As part of these temporary security measures, some website functions may experience limitations, particularly: Uploading larger files, such as images, videos and documents. Submitting larger forms or importing data. Restoring backups or performing website migrations. Installing themes or plugins that require file uploads. The impact may vary depending on your server and the functionality being used. Smaller uploads and routine website operations may continue to work normally. What happens next? Our teams are working with our software providers to deploy the appropriate security updates as soon as they become available. Once the permanent fixes are ready and installed, the temporary restrictions can be reviewed and removed. We expect this process to take a few days, although the timeframe may vary depending on the PHP version and availability of the required updates. We’ll share further updates as more information becomes available. We understand that these temporary limitations may cause inconvenience, and we appreciate your patience while we work to address the vulnerabilities. These measures have been implemented as a precaution to help maintain a secure hosting environment. Thank you for your understanding and for trusting us to host your websites. Our commitment remains the same: keeping your hosting environment secure while minimising disruption to your services.

   We’re pleased to share that PHP security patching has been completed across our shared Linux hosting environment to address the vulnerabilities CVE-2026-109618 and CVE-2026-109619. As an additional precaution, the temporary security mitigation limits applied earlier remain in place while we continue working to fully mitigate the risk. These limits may temporarily affect certain file uploads, large form submissions, and backup restores. Our teams are continuing to monitor the environment closely. We will provide further updates once the remaining restrictions can be safely removed. Thank you for your patience, understanding, and continued trust in us as we work to keep your hosting environment secure.
