Wava Payment 0.3.1 - 0.3.9 - Unauthenticated Merchant Credential Overwrite via Install Webhook

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 Wava Payment Plugin WordPress plugin before 0.3.10 does not perform any authorisation, nonce or origin verification on one of its public REST endpoints, allowing unauthenticated attackers to overwrite the stored credential that identifies the merchant account the store's payments are created against, to force the integration into a verified state the site owner never completed, and to remove the payment method from the store's checkout.
