Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 70.0.3538.67

Description The issue arises from insufficiently strict origin checks during the installation of the JIT payment app in Google Chrome. This allowed a remote attacker to install a service worker for a domain that can host attacker-controlled files via a crafted HTML page.

Recommendations For versions prior to 70.0.3538.67, update to version 70.0.3538.67 or later to resolve the issue. As a temporary workaround, consider restricting access to the JIT payment app installation feature until the update is applied.
