CVE-2026-15213
MediumCVSS 5.3Summary
The Welcart e-Commerce WordPress plugin before 2.11.33 does not verify the authenticity of its convenience-store / bank-transfer settlement callback: an unauthenticated request can flip an order from unpaid to settled purely from an order number and a status flag, with no signature, amount, or origin check. Because these are pay-later methods, an attacker can mark their own unpaid order as settled and obtain fulfilment without paying.
Risk Assessment
The risk includes order fulfillment without payment, leading to financial losses and abuse.
Recommendation
It is recommended to immediately update the plugin to version 2.11.33 or later and implement verification of signature, amount, and origin of the callback.
