The security team should also review the current incident response plan to ensure that it,

Technical summary

The Sylius Mollie Plugin provides Mollie payment integration for Sylius applications. Prior to versions 2.2.8, 3.2.4, and 3.3.1, the plugin's GET /{_locale}/thank-you PageRedirectController::thankYouAction and GET /{_locale}/get-code QrCodeAction::fetchQrCodeFromOrder endpoints do not perform ownership or session checks when looking up sequential orderId values. This exposes order tokenValue values that can be used with GET /{_locale}/register-after-checkout/{tokenValue} to view customer first name, last name, and email.

• Review and restrict access to GET /{_locale}/thank-you and GET /{_locale}/get-code endpoints
• Monitor for suspicious activity on customer registration and checkout pages
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
