Technical Analysis
CVE-2026-79630 is an authorization bypass vulnerability in the WPFunnels WordPress plugin prior to version 3.13.0. The plugin fails to verify that the product requested through a checkout order bump matches the product for which the discount was configured. This allows unauthenticated attackers to manipulate the order bump mechanism to purchase products at discounts not intended for them, affecting the integrity of pricing during checkout.
Potential Impact
The vulnerability allows unauthenticated users to obtain discounts on any purchasable product by exploiting the order bump feature, leading to potential financial loss due to unauthorized discounted purchases. There is no impact on confidentiality or availability reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should monitor vendor communications for updates and consider disabling the order bump feature if feasible to reduce risk.
