CVE-2026-54815: Cargo Shipping Location SQLi Vulnerability

CVE-2026-54815 Overview

CVE-2026-54815 is a blind SQL injection vulnerability in the Cargo Shipping Location for WooCommerce WordPress plugin developed by Cargo RD. The flaw stems from improper neutralization of special elements used in SQL commands [CWE-89]. Unauthenticated attackers can inject malicious SQL statements over the network without user interaction. The vulnerability affects all plugin versions from initial release through 5.6. Successful exploitation enables data extraction from the WordPress database backing the affected WooCommerce store.

Critical Impact
Unauthenticated network-based SQL injection allows attackers to extract sensitive database contents from WooCommerce stores using vulnerable versions of the plugin.

Affected Products

Cargo Shipping Location for WooCommerce plugin versions through 5.6
WordPress sites running WooCommerce with this plugin installed
E-commerce stores using Cargo RD shipping integration

Technical Details for CVE-2026-54815

Vulnerability Analysis

The vulnerability is classified under [CWE-89], Improper Neutralization of Special Elements used in an SQL Command. The plugin fails to sanitize user-supplied input before incorporating it into SQL queries. Attackers can manipulate query logic by injecting crafted payloads through accessible plugin endpoints.

This is a blind SQL injection variant. The application does not return query results or database errors directly to the attacker. Instead, attackers infer data by observing boolean responses or time-based delays in server replies. Refer to the Patchstack WordPress SQL Injection Advisory for technical details.

Root Cause

The root cause is the absence of parameterized queries or proper input sanitization before SQL execution. User-controlled parameters reach the database layer concatenated into raw SQL statements. WordPress provides the $wpdb->prepare() function for safe query construction, which the affected code paths fail to use correctly.

Attack Vector

The attack vector is network-based with no authentication or user interaction required. An attacker sends crafted HTTP requests to vulnerable plugin endpoints exposed by the WordPress site. The scope is changed because successful exploitation can impact resources beyond the vulnerable component, including the broader WordPress database. The vulnerability mechanism is described in prose because no verified proof-of-concept code is publicly available.

Detection Methods for CVE-2026-54815

Indicators of Compromise

Unusual HTTP requests to Cargo Shipping Location for WooCommerce plugin endpoints containing SQL keywords such as UNION, SELECT, SLEEP, or BENCHMARK
Web server access logs showing parameter values with encoded quotes, comments (--, #), or conditional logic patterns
Spikes in database query latency consistent with time-based blind injection probes

Detection Strategies

Deploy web application firewall rules that flag SQL injection patterns targeting plugin request parameters
Monitor WordPress database for unexpected SELECT statements originating from plugin code paths
Correlate slow database queries with concurrent inbound requests to plugin URLs

Monitoring Recommendations

Enable verbose logging on the WordPress site and forward logs to a centralized analytics platform
Track repeated requests from a single source IP with varying parameter payloads
Alert on outbound database connection anomalies or unexpected schema enumeration activity

How to Mitigate CVE-2026-54815

Immediate Actions Required

Identify all WordPress instances running Cargo Shipping Location for WooCommerce version 5.6 or earlier
Disable or uninstall the plugin until a patched release is verified and applied
Restrict access to WooCommerce administrative endpoints behind authentication or IP allowlists
Review database audit logs for evidence of unauthorized query activity

Patch Information

At the time of publication, no fixed version is referenced in the NVD record. Consult the Patchstack WordPress SQL Injection Advisory for the latest remediation guidance and updated plugin releases.

Workarounds

Deploy a web application firewall with SQL injection signatures covering WordPress plugin parameters
Apply virtual patching rules at the reverse proxy or WAF layer to block known injection payloads
Enforce least-privilege database accounts so the WordPress user cannot read sensitive tables beyond what is required
Rotate WordPress credentials, API keys, and secrets that may have been exposed through the database

bash

# Example WAF rule concept blocking common SQL injection tokens in query strings
# (adapt to your WAF syntax, e.g., ModSecurity, AWS WAF, Cloudflare)
SecRule ARGS "@rx (?i)(union(\s|/\*.*\*/)+select|sleep\s*\(|benchmark\s*\(|--\s|;--|/\*!)" \
