【Notice】Impact of PHP Vulnerabilities on “GO SUB”

We are providing an update on the current status of the impact of the PHP vulnerability disclosed on October 21, 2026, on GO SUB, our subscription app.

1. Whether we are affected
GO SUB does not use PHP in either the application itself or its API integration with Shopify. We therefore believe this vulnerability does not affect us. This assessment is based on a review of our development and infrastructure setup (application, dependent libraries, and hosting environment).

2. Security Measures Implemented
As we are not affected, no fixes or countermeasures are necessary in response to this vulnerability. “GO SUB” is built on a technology stack other than PHP, and the latest security patches for the underlying software had been applied as of October 22.

3. Status of Checks for Unauthorized Access
At this time, we have found no signs of unauthorized access or information leaks resulting from exploitation of this vulnerability.

4. Actions Required from Customers
No action is required in connection with this matter, such as temporarily suspending apps or API integrations, changing settings, or updating authentication credentials. You can continue using “GO SUB” safely as usual.
