Short explanation
The WordPress plugin through version 3.1 does not verify the origin of payment‑confirmation requests and derives its verification key from an empty value on a default install, allowing unauthenticated attackers to forge confirmations and mark any WooCommerce order as paid.
Attackers can complete orders without payment, causing financial loss and eroding trust in the affected site.
What should be done?
- Apply vendor‑released patch when available
- Manually configure a non‑empty verification key
- Add checks to validate webhook source
- Keep the plugin up‑to‑date
- Remove the plugin if not required
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.
