CVE-2026-11575: CWE-862 Missing Authorization in PhonePe Payment Solutions
The PhonePe Payment Solutions WordPress plugin before 3.1.0 does not properly verify the authenticity of incoming payment callbacks: the secret used to validate the callback signature is empty on sites configured through the current setup flow, so the expected signature reduces to an unkeyed hash of the request body that anyone can compute. This allows unauthenticated attackers to forge a payment-success notification and mark unpaid WooCommerce orders as paid without any payment being made.
AI Analysis
Technical Summary
CVE-2026-11575 is a missing authorization vulnerability (CWE-862) in the PhonePe Payment Solutions WordPress plugin prior to version 3.1.0. The vulnerability arises because the secret used for validating payment callback signatures is empty on sites configured with the current setup flow, reducing the signature to an unkeyed hash of the request body. This flaw allows unauthenticated attackers to forge payment-success callbacks, thereby marking unpaid WooCommerce orders as paid without any legitimate payment transaction.
