CVE-2026-87837 Details
Description
The Wava Payment Plugin WordPress plugin before 0.3.10 does not verify the authenticity of incoming payment-provider notifications, nor restrict who may send them, allowing unauthenticated attackers to change the status of any WooCommerce order in the store, including marking an unpaid order as paid and completed, and cancelling other customers' orders. In versions up to 0.3.7 the response additionally returns the affected order's billing details, disclosing customer names, addresses, email addresses and phone numbers to the same unauthenticated caller.
A vulnerability exists in the Wava Payment Plugin for WordPress, specifically in versions prior to 0.3.10. The plugin fails to authenticate incoming payment notifications and does not restrict who can send them. This allows unauthenticated attackers to manipulate the status of any WooCommerce order, such as marking an unpaid order as paid and completed, or cancelling other customers' orders. Additionally, in versions up to 0.3.7, the plugin inadvertently disclosed sensitive customer information, including names, addresses, email addresses, and phone numbers, to the unauthenticated caller.
Users are advised to update the Wava Payment Plugin to version 0.3.10 or later.
