Casso Auto-confirm Bank Transfer < 4.2.0 - Unauthenticated WooCommerce Order Payment Confirmation

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 Casso Flow WordPress plugin before 4.2.0 does not properly authenticate incoming bank-transfer payment notifications, as the token used to verify them is empty on a default installation, allowing unauthenticated attackers to forge a notification and mark any pending WooCommerce order as paid, regardless of its payment method.
