## Affected

- Unknown Coinsnap Bitcoin Crowdfunding: through 1.2.0

## Description

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.
