CVE-2026-42664: AI Product Search for WooCommerce – Motive Commerce Search <= 1.38.2 – Missing Authorization (motive-commerce-search)

CVE ID CVE-2026-42664
Plugin motive-commerce-search
Severity Medium (CVSS 5.3)
CWE 862
Vulnerable Version 1.38.2
Patched Version 1.38.3
Disclosed May 8, 2026

Analysis Overview

Atomic Edge analysis of CVE-2026-42664:

This vulnerability involves missing authorization in the AI Product Search for WooCommerce – Motive Commerce Search plugin versions up to and including 1.38.2. The core issue lies in REST API endpoints registered in class-motive-public.php that allowed unauthenticated access to sensitive configuration and schema data due to the use of ‘__return_true’ as the permission callback.

Root Cause: The plugin registers multiple REST API endpoints in the ‘motive/v1’ namespace within the file motive-commerce-search/public/class-motive-public.php. The endpoints for ‘info’ (line 126), ‘(?P.+)/schema’ (line 140), ‘config’ via GET (line 157), ‘config’ via POST (line 173), and ‘config-if-unset’ via POST (line 189) all used ‘permission_callback’ => ‘__return_true’. This PHP callback unconditionally returns true, granting access to any user or unauthenticated visitor. The patched version replaces each with ‘permission_callback’ => array( $this, ‘is_authorized_request’ ), introducing a new method that verifies a security token from the request header.

Exploitation: An attacker can send direct HTTP GET or POST requests to any of the vulnerable REST API endpoints without authentication. For example, accessing ‘/wp-json/motive/v1/info’ returns plugin configuration and system information. The endpoint ‘/wp-json/motive/v1/config’ can be read or written via GET/POST, allowing an attacker to retrieve and modify plugin settings. The ‘(?P.+)/schema’ endpoint exposes the search schema definitions. No authentication cookies, nonces, or tokens are required.

Patch Analysis: The patch changes the permission_callback from ‘__return_true’ to ‘is_authorized_request’ for all five endpoints. The new method (added at line 307) calls ‘Token::check()’ with the value of the custom header ‘MOTIVE_TOKEN’ (likely defined as HEADER_MOTIVE_TOKEN). The token-based authentication ensures only requests with a valid security token can access these endpoints. Additionally, the patch includes SQL injection hardening in multiple builder classes (e.g., AttributeValueBuilder, FeatureValueBuilder, ImageBuilder, MultipleQueryProductBuilder) by replacing direct variable interpolation with prepared statements using $wpdb->prepare(). The patch also adds ABSPATH checks to prevent direct file access.

Impact: Unauthenticated attackers can read sensitive plugin configuration data, including API endpoints and internal settings, by accessing the ‘config’ and ‘info’ endpoints. They can also modify plugin configuration via POST requests to the ‘config’ endpoint, potentially altering search behavior, prices, and other e-commerce functionality. The schema endpoint exposes the data structure used for product indexing. This information disclosure and configuration manipulation could lead to further attacks against the WooCommerce store.
