Covers the Japanese Mercari marketplace app and web version developed and operated by the Japanese company Kabushiki Kaisha Mercari. Overseas services and services run by separate legal entities are outside this page’s scope.

A response to the PHP vulnerability has not been verified. The official update at 09:12 on October 22 cancelled the proposed maintenance after a safety check concerning an external software vulnerability, reporting normal app and web availability. It does not identify the software, PHP or the relevant CVE, so it does not establish PHP remediation.

Scope: No response information means that an official response to the PHP vulnerability has not been verified. It does not establish inaction, absence of impact or completed remediation. PHP use itself has not been verified.

This recheck could not revalidate all listed information against current official sources. The previous verification date is retained. Check official notices or support for current availability and required action.

What users should do

Check official notices and in-app guidance for the availability of the features you use and any instructions for users. Ask the operator about the specific service if you need confirmation of PHP remediation.
