CVE-2026-14639: CodeAstro Ecommerce Website SQL Injection

CVE-2026-14639 Overview

CVE-2026-14639 is a SQL injection vulnerability in CodeAstro Ecommerce Website 1.0. The flaw resides in the /ecommerce-website-php/customer/my_account.php?edit_account endpoint. Attackers can manipulate the c_name parameter to inject arbitrary SQL statements into the backend database query.

The vulnerability is remotely exploitable and requires only low-level privileges to trigger. Public disclosure of the exploit details has occurred, increasing the risk of opportunistic attacks against exposed installations. The weakness is classified under [CWE-74] Improper Neutralization of Special Elements in Output Used by a Downstream Component (Injection).

Critical Impact
Authenticated attackers can inject SQL statements through the c_name parameter to read, modify, or exfiltrate customer account data from the underlying database.

Affected Products

CodeAstro Ecommerce Website 1.0
/ecommerce-website-php/customer/my_account.php component
edit_account functionality via the c_name parameter

Technical Details for CVE-2026-14639

Vulnerability Analysis

The vulnerability exists in the account editing workflow of the CodeAstro Ecommerce Website PHP application. When a customer submits changes to their account through my_account.php?edit_account, the application accepts the c_name parameter and incorporates its value directly into a SQL query without proper sanitization or parameterization.

An attacker with a valid customer session can supply crafted input containing SQL metacharacters. The backend concatenates this input into the query string, allowing the injected clauses to execute against the database. Impact includes unauthorized data access, tampering with account records, and potential extraction of sensitive customer information stored in the ecommerce database.

The issue affects confidentiality, integrity, and availability at a limited scope, since the attacker must first authenticate as a low-privileged customer to reach the vulnerable endpoint.

Root Cause

The root cause is improper neutralization of user-controlled input passed to a SQL query. The c_name parameter is not validated, escaped, or bound as a parameter before being included in the query executed by the database driver. This pattern of building queries through string concatenation is the underlying weakness described by [CWE-74].

Attack Vector

An attacker authenticates to the ecommerce application as a customer and sends a crafted HTTP request to /ecommerce-website-php/customer/my_account.php?edit_account. The c_name field in the request body carries the SQL injection payload. Because the application does not filter or parameterize this value, the injected SQL executes with the privileges of the application database user. Refer to the GitHub CVE Issue Discussion and VulDB CVE-2026-14639 entry for the disclosed proof-of-concept details.

Detection Methods for CVE-2026-14639

Indicators of Compromise

HTTP POST requests to /ecommerce-website-php/customer/my_account.php?edit_account containing SQL metacharacters such as single quotes, UNION SELECT, OR 1=1, or comment sequences (--, #) in the c_name field.
Database error messages or stack traces returned in HTTP responses following edit_account requests.
Abnormal database query volume or latency spikes traced back to the customer account module.

Detection Strategies

Enable verbose web server access logging and search for suspicious c_name parameter values containing SQL keywords.
Deploy a web application firewall (WAF) rule targeting SQL injection patterns in the edit_account request parameters.
Correlate authenticated customer session activity against database audit logs to identify anomalous query structures originating from my_account.php.

Monitoring Recommendations

Alert on repeated 500-series HTTP responses from the my_account.php endpoint, which often indicate injection probing.
Monitor database accounts used by the ecommerce application for INFORMATION_SCHEMA reads or cross-table queries that fall outside normal application behavior.
Track authentication events followed immediately by malformed edit_account submissions to identify credential-stuffed injection attempts.

How to Mitigate CVE-2026-14639

Immediate Actions Required

Restrict access to /ecommerce-website-php/customer/my_account.php behind a WAF configured to block SQL injection payloads targeting the c_name parameter.
Audit the ecommerce database for unexpected data modifications or new administrative records created after the disclosure date.
Rotate the database credentials used by the ecommerce application and enforce least-privilege permissions for that account.

Patch Information

No official vendor patch is referenced in the CVE data at the time of publication. Administrators should monitor the CodeAstro Security Tools site and the GitHub CVE Issue Discussion for remediation updates. Until a fix is released, apply the workarounds below and consider taking the affected functionality offline for high-risk deployments.

Workarounds

Modify my_account.php to use parameterized queries or PDO prepared statements when handling the c_name value.
Add server-side input validation that rejects non-alphanumeric characters in the c_name field before it reaches the database layer.
Deploy virtual patching through a WAF rule that blocks requests to edit_account containing SQL syntax tokens.
