CVE-2026-92427 Details
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.
A vulnerability exists in the Coinsnap Bitcoin Crowdfunding WordPress plugin, affecting versions through 1.2.0. The plugin fails to restrict access to the secret used for authenticating payment gateway webhooks, allowing unauthenticated users to access it. This oversight disables the webhook's signature verification, enabling unauthenticated attackers to fabricate payment confirmation notifications. As a result, attackers can record arbitrary donations as completed, specifying the amounts, donor names, and messages.
