CVE-2026-14639: SQL Injection in CodeAstro Ecommerce Website 1.0 – Patch Guidance

Technical summary

The vulnerability exists in /ecommerce-website-php/customer/my_account.php when processing the edit_account function. The 'c_name' parameter is not properly sanitized or parameterized before being included in SQL queries, allowing an authenticated user to execute arbitrary SQL commands. This is classified as CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) with elements of CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The attack requires authentication (CVSS metric PR:L), no user interaction, and affects only the targeted application instance (S:U), resulting in a CVSS 3.1 base score of 6.3 (Medium severity).

Business impact

If exploited, this vulnerability could allow attackers with valid user accounts to read sensitive customer data (names, contact information, purchase history), modify order information or account credentials, or disrupt application availability. For ecommerce operations, data tampering poses regulatory compliance risks (PCI-DSS, GDPR) and reputational damage. The public disclosure increases the likelihood of opportunistic exploitation, making this a business continuity concern even at Medium severity.

Affected systems

CodeAstro Ecommerce Website version 1.0 is confirmed affected. The vulnerability specifically impacts the customer account editing functionality accessible through the my_account.php script. Any organization running this application version with active customer accounts is potentially exposed.

Exploitability

The vulnerability is exploitable with low complexity and has been publicly disclosed, meaning exploit proof-of-concept details are available. However, exploitation requires valid authentication credentials—an attacker must first obtain or compromise a customer account. This moderates the risk compared to unauthenticated SQL injection but does not eliminate it, as many ecommerce sites allow self-registration and attackers can create test accounts to gain initial access.

Remediation

Immediately upgrade CodeAstro Ecommerce Website to a patched version addressing this vulnerability. Verify the exact patch version number in the vendor's official advisory. If an immediate upgrade is not feasible, implement input validation and parameterized queries (prepared statements) for the affected my_account.php script to prevent SQL injection. Additionally, restrict access to the edit_account function to authorized users only and monitor SQL error logs for injection attempts.

Patch guidance

Contact CodeAstro directly or consult their official security advisory to confirm the patched version number and download procedure. Apply patches in a test environment first to verify compatibility with your ecommerce configuration. Ensure backups are current before deploying patches to production. If upgrading from version 1.0, review any custom modifications that may conflict with the patch.

Detection guidance

Monitor application logs for SQL error messages, unusual SQL syntax in request parameters (especially the c_name field), and suspicious activity from authenticated user accounts. Web application firewalls (WAF) can be configured to detect and block common SQL injection patterns in the my_account.php endpoint. Review database query logs for unexpected commands executed by the application user account. Regularly audit user account creation and privilege changes to identify compromise.

Why prioritize this

Although classified as Medium severity, this vulnerability merits expedited attention because it has been publicly disclosed, which increases exploitation risk, and because it directly impacts customer data. Any delay in patching compounds regulatory and reputational exposure in an ecommerce context. The requirement for authentication provides a modest control but should not be relied upon as the sole mitigation.

Risk score, explained

The CVSS 3.1 score of 6.3 reflects the combination of remote attack vector, low attack complexity, and the requirement for authenticated access. The vulnerability can impact confidentiality, integrity, and availability equally (each rated as Low due to the scope being unchanged). This 'Medium' rating appropriately represents a meaningful but not critical risk—higher than many low-impact issues but below high-severity flaws that allow unauthenticated data exfiltration or remote code execution.
