2 techniques across 2 tactics: Initial Access, Persistence

The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

The attacker must be authenticated as an administrator or a user with the 'manage_options' capability on the WordPress site. The vulnerable 'id' parameter must be present in requests to scripts such as sms_campaign.php, class-abandonedcart.php, or SMSAlert-wc-order-sms.php. The attack is network-based and requires no user interaction. Default configurations are affected, but only admin-level users can trigger the vulnerability.

Impact

The CVSS score is 4.9 (medium) with a vector indicating network attack vector, low complexity, high privileges required (admin), no user interaction, and a confidentiality impact only. This means an attacker must already have admin-level access to the WordPress site to exploit it, which limits the attack surface. No EPSS or KEV data is available, suggesting low exploitation likelihood. However, if an attacker obtains admin credentials (e.g., via phishing or credential theft), they can extract the entire database. The SSVC decision would rate exploitation status as 'none', automatable as 'yes' (for an admin), and technical impact as 'high' (data exfiltration). Overall, it is a moderate priority for sites with strict admin access controls.

Exploit ScenarioDerived

An attacker who has obtained administrator credentials to a vulnerable WordPress site sends a crafted HTTP request to the vulnerable endpoint with a malicious SQL payload in the 'id' parameter. The injection allows the attacker to extract the entire WordPress database, including user passwords, customer data, and WooCommerce order details.

AnalysisAIv1 – Jul 28, 2026

SQL injection in the SMS Alert WordPress plugin allows authenticated administrators to extract sensitive database information. Affected versions up to and including 3.9.7 are vulnerable via the 'id' parameter. No active exploitation or public exploit has been reported as of this analysis.

RemediationAI

Upgrade the plugin to the latest patched version (likely 3.9.8 or higher) as soon as possible. A fix has been committed to the WordPress plugin repository as shown in the changeset reference. As a workaround, limit administrator access to only trusted users, enforce strong passwords, and consider enabling two-factor authentication for WordPress admin accounts. No other workarounds exist short of disabling or removing the plugin entirely.

Technical ContextAI · show details

The SMS Alert plugin integrates with WooCommerce for SMS notifications, OTP, and abandoned cart recovery. The vulnerability is a classic SQL injection (CWE-89) in multiple PHP scripts, including sms_campaign.php and class-abandonedcart.php, where the 'id' parameter is concatenated into SQL queries without proper escaping or prepared statements. The CPE (cpe:2.3:a:cozyvision1:sms_alert_-_sms_&_otp_for_woocommerce,_order_notifications_&_abandoned_cart_recovery:*:*:*:*:*:*:*) confirms all versions up to the fixed one are affected.

DescriptionCVE.org

The SMS Alert - SMS & OTP for WooCommerce, Order Notifications & Abandoned Cart Recovery plugin for WordPress is vulnerable to generic SQL Injection via the 'id' parameter in all versions up to, and including, 3.9.7 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
