Published Sep 8, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
Description

This makes it possible for unauthenticated attackers to overwrite the site's Stripe merchant credentials (access tokens, publishable keys, and account ID), diverting all subsequent payment processing to the attacker's Stripe account.
