CVE-2026-14767 Overview
CVE-2026-14767 is a SQL injection vulnerability in CodeAstro Ecommerce Website 1.0. The flaw resides in /ecommerce-website-php/customer/confirm.php within the POST parameter handler. Attackers can manipulate the invoice_no argument to inject arbitrary SQL statements. The vulnerability requires low-level authenticated access and can be exploited remotely without user interaction. A public proof-of-concept has been released, increasing the likelihood of opportunistic exploitation against exposed installations. The weakness is classified under [CWE-74] as improper neutralization of special elements in output used by a downstream component (injection).
Critical Impact
Authenticated remote attackers can inject SQL through the invoice_no POST parameter, potentially reading, modifying, or deleting data in the ecommerce backend database.

Technical Details for CVE-2026-14767
Vulnerability Analysis
The vulnerability exists in the customer order confirmation workflow of CodeAstro Ecommerce Website 1.0. The application accepts the invoice_no value from a POST request and passes it into a SQL query without proper sanitization or parameterization. An authenticated customer can supply crafted SQL syntax in that parameter to alter the query's structure. Successful exploitation exposes the underlying database to unauthorized read and write operations. Because confirmation endpoints typically reference order, payment, and account tables, the injection surface reaches sensitive business data.
Root Cause
The root cause is direct concatenation of user-supplied input into a SQL statement inside confirm.php. The handler does not use prepared statements, parameter binding, or type coercion for the invoice_no field. Any string submitted through the POST body is trusted as part of the query context, satisfying the conditions described in [CWE-74].
Attack Vector
Exploitation requires network access to the application and a valid low-privilege customer session. The attacker submits a crafted POST request to /ecommerce-website-php/customer/confirm.php with a malicious invoice_no payload such as a boolean-based or UNION-based SQL injection string. The server evaluates the injected SQL against the backend database and returns manipulated results or performs unintended writes. Details of the proof-of-concept payload are documented in the GitHub Gist PoC Repository and the VulDB CVE-2026-14767 entry.
No verified exploit code is reproduced here. Refer to the published references for technical payload details.
Detection Methods for CVE-2026-14767
Indicators of Compromise
- POST requests to /ecommerce-website-php/customer/confirm.php containing SQL metacharacters such as single quotes, UNION, SELECT, --, or OR 1=1 in the invoice_no field.
- Web server access logs showing repeated confirm.php submissions from the same source with varying invoice_no values.
- Database error messages returned in HTTP responses that reference SQL syntax faults from the confirmation flow.
Detection Strategies
- Deploy web application firewall (WAF) signatures targeting SQL injection patterns against the invoice_no parameter.
- Enable verbose HTTP request logging on the ecommerce host and alert on non-numeric values submitted for invoice_no.
- Correlate authentication events with anomalous POST payload sizes or encoded characters directed at confirm.php.
Monitoring Recommendations
- Monitor the backend database for unusual query patterns originating from the ecommerce application account, particularly queries containing tautologies or unbounded SELECT statements.
- Track failed and slow SQL queries associated with the invoice confirmation workflow.
- Alert on privilege changes, new user creation, or bulk data reads that follow suspicious HTTP activity against confirm.php.
How to Mitigate CVE-2026-14767
Immediate Actions Required
- Restrict network exposure of the CodeAstro Ecommerce Website 1.0 deployment until a fix is applied, using access control lists or VPN gating.
- Audit the confirm.php handler and replace string-concatenated SQL with prepared statements that bind invoice_no as an integer.
- Review database logs for evidence of prior injection attempts referenced by the public proof-of-concept.
- Rotate database credentials used by the application if compromise is suspected.
Patch Information
No vendor patch has been published in the referenced advisories at the time of NVD publication on 2026-07-05. Consult the CodeAstro Security Resource for vendor updates and the VulDB Vulnerability #376357 entry for tracking remediation status.
Workarounds
- Enforce strict server-side input validation on invoice_no, rejecting any value that is not a positive integer matching the expected invoice format.
- Deploy a WAF rule that blocks SQL metacharacters in POST parameters submitted to /ecommerce-website-php/customer/confirm.php.
- Apply least-privilege permissions to the database account used by the ecommerce application, removing DDL and multi-statement execution rights.
- Disable verbose SQL error output in the application to reduce information available to attackers probing the endpoint.
