WP Stripe Checkout < 1.2.2.62 - Unauthenticated Forged Payment Completion via an Unset Webhook Signing Secret

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

The WP Stripe Checkout WordPress plugin before 1.2.2.62 does not verify the Stripe webhook signature when no signing secret is configured, which is its default state, allowing unauthenticated attackers to forge a payment completion notification and create a completed order without paying.
