This CVE was published Aug 27, 2026 and is one of 1 known issue for this plugin.
Update, patch or deactivate.
Update to 2.1.2 or later and reconcile BOGO orders, line-item prices, payment receipts, and fulfillment for underpayment.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
