Summary

The Coinsnap Bitcoin Crowdfunding WordPress plugin through 1.2.0 does not restrict access to the secret used to authenticate its payment gateway webhook, disclosing it to unauthenticated users and rendering the webhook's signature check ineffective. This allows unauthenticated attackers to forge payment-confirmation notifications and record arbitrary donations as completed, with attacker-chosen amounts, donor names and messages.

Risk Assessment

An attacker can forge payment confirmations and mark non-existent donations as paid, leading to financial losses and falsification of crowdfunding campaign data. This can also compromise the integrity of donation records.

Recommendation

Update the Coinsnap Bitcoin Crowdfunding plugin to a version newer than 1.2.0 when available, and in the meantime consider disabling the plugin or configuring the webhook secret securely.
