CVE-2026-14767: CodeAstro Ecommerce Website SQL Injection Vulnerability

Technical summary

CVE-2026-14767 is a SQL injection flaw residing in the POST Parameter Handler of /ecommerce-website-php/customer/confirm.php. The invoice_no parameter fails to properly sanitize or parameterize user input before constructing SQL queries, allowing authenticated users to inject arbitrary SQL syntax. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). With a CVSS v3.1 score of 6.3 (Medium severity), the attack vector is network-based, requires login credentials, and results in partial confidentiality, integrity, and availability impact.

Business impact

Organizations running CodeAstro Ecommerce Website 1.0 face moderate but real operational risk. An authenticated customer or employee could read sensitive order data, customer records, or payment information; modify order history or pricing; or degrade database performance through malicious queries. For retail or SaaS platforms, this could expose customer PII, disrupt order processing, and trigger regulatory notification obligations under GDPR or similar frameworks.

Affected systems

CodeAstro Ecommerce Website version 1.0 is the confirmed affected product. Organizations should audit for this version in production, development, and staging environments. Assess whether the /customer/confirm.php endpoint is accessible to authenticated users and whether database credentials powering the application have broad privileges.

Exploitability

This vulnerability has a moderate exploit barrier. It requires valid login credentials, limiting the attack surface to known or compromised user accounts. However, public exploit code is now available, reducing the technical skill required to weaponize the flaw. The remote, network-accessible nature and lack of complex interaction requirements mean that any authenticated user—including low-privilege customers—could attempt exploitation with minimal effort.

Remediation

Implement SQL parameterized queries (prepared statements) in the confirm.php handler to separate SQL logic from user input. Apply input validation to the invoice_no parameter, accepting only expected formats (e.g., alphanumeric or numeric). Apply principle of least privilege to database connection credentials. Consider a Web Application Firewall rule to detect and block obvious SQL injection patterns. As a short-term control, restrict access to the /customer/ endpoint to trusted IP ranges or add additional authentication layers.

Patch guidance

Verify with CodeAstro's official security advisory and update documentation for patch availability and version numbers—SEC.co has not confirmed a patched version in the vendor release data. Contact CodeAstro directly or monitor their security bulletins for guidance. If the product is unmaintained or no patch is forthcoming, prioritize migration to an actively supported ecommerce platform.

Detection guidance

Monitor web server logs and WAF rules for POST requests to /ecommerce-website-php/customer/confirm.php containing SQL keywords (SELECT, UNION, OR, AND, --) in the invoice_no parameter. Enable database query logging to identify anomalous SQL patterns. Look for error messages reflecting SQL syntax issues in application logs, which may indicate failed injection attempts. Baseline normal invoice_no values and alert on deviations.

Why prioritize this

Although the CVSS score is Medium (6.3), public exploit availability and the straightforward attack vector warrant prompt attention. Combined with e-commerce context—where databases typically hold sensitive customer and transaction data—this should be scheduled within your standard patch cycle (typically 30 days for medium-severity authenticated SQL injection).

Risk score, explained

The CVSS v3.1 score of 6.3 reflects: (1) network-accessible attack vector with low complexity; (2) requirement for user authentication (reduces severity); (3) partial compromise of confidentiality, integrity, and availability. The score does not capture that public exploits are available; factor that into your risk assessment independently. Organizations handling PII or payment card data may justify higher internal risk ratings despite the baseline CVSS.
