Vulnerabilities (CVE-2026-109618, CVE-2026-109619) have been disclosed in PHP. Since websites using PHP (such as WordPress) may be affected, we are currently checking the status of websites for our clients that we create and operate.

As of the publication of this notice, the following corrected versions are available from the PHP developer (php.net).

• PHP 8.5.12
• PHP 8.4.27
• PHP 8.3.36
• PHP 8.2.35

Official support for PHP versions prior to 8.1 has ended, and no updates are provided by the developer.For details, please see the official announcement on php.net.Please check it.

Regarding the responses of each hosting company

Each hosting company is sequentially implementing the following measures:

• Update the server's PHP to the corrected version.
• We also apply our own fixes to older versions whose official support has ended.
• For security reasons, some websites will be temporarily taken down.

Some hosting companies apply their own fixes to older versions, so even if the displayed version is old, the fix may already be applied. The content and timing of the fixes vary from hosting company to hosting company, so please check the information provided by your hosting company for the latest status.

Regarding the scope of our services

Upgrading the PHP version on the server itself is the responsibility of the hosting provider. Therefore, we cannot perform the PHP upgrade ourselves.

We will take the following actions:

• Check the PHP version of the website you are responsible for and the support status of each hosting company.
• Contacting customers based on the verification results
• Consultation regarding checking and modifying website display and functionality following PHP version changes.

A request to our customers

• Please check the instructions from your hosting provider.
• If you need to change your PHP version, please do so through your hosting provider's control panel or similar.
• Changing versions may cause some parts of the website to display incorrectly. If you have any questions before or after the change, please contact our representative.
• If you experience issues such as the website not displaying correctly, please contact our representative.
