CVE-2026-14799: CodeAstro Ecommerce SQLi Vulnerability

CVE-2026-14799 Overview

CVE-2026-14799 is a SQL injection vulnerability affecting CodeAstro Ecommerce Website 1.0. The flaw resides in the /customer/my_account.php?my_wishlist endpoint, where the delete_wishlist parameter is not properly sanitized before being incorporated into a database query. An authenticated remote attacker can manipulate this parameter to alter query logic and interact with the underlying database. The exploit has been publicly disclosed, increasing the likelihood of opportunistic abuse against exposed installations. This weakness is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Remote attackers with low-privilege access can inject SQL into the delete_wishlist parameter to read or modify customer data stored in the ecommerce database.

Affected Products

CodeAstro Ecommerce Website 1.0
Deployments exposing /customer/my_account.php?my_wishlist
Downstream forks reusing the vulnerable wishlist handler

Technical Details for CVE-2026-14799

Vulnerability Analysis

The vulnerability exists in the wishlist deletion routine served by /customer/my_account.php?my_wishlist. The application accepts a delete_wishlist argument from the client and concatenates it directly into a SQL statement without parameterization or input validation. This allows an attacker to break out of the intended query context and append arbitrary SQL clauses.

Because the endpoint sits behind customer authentication, an attacker needs a valid low-privilege account to reach the injection point. Account creation is typically self-service on ecommerce platforms, which lowers the barrier to reaching the vulnerable code path. The exploit has been released publicly, giving attackers a working reference for automated abuse.

Successful exploitation can expose customer records, order histories, credentials, and other data stored in the backing database. Depending on the database user's privileges, attackers may also modify records or pivot to other tables.

Root Cause

The root cause is the absence of prepared statements or input sanitization in the wishlist deletion handler. The delete_wishlist argument is passed from the HTTP request into a dynamically constructed SQL query, which is the classic pattern associated with [CWE-74] injection flaws.

Attack Vector

The attack is delivered over the network against the customer-facing PHP endpoint. An authenticated user submits a crafted value for delete_wishlist through a GET or POST request. The malicious payload is interpreted as SQL by the backend database, executing attacker-controlled logic. No user interaction beyond the attacker's own session is required.

Detection Methods for CVE-2026-14799

Indicators of Compromise

Requests to /customer/my_account.php?my_wishlist containing SQL metacharacters such as ', ", --, ;, or UNION in the delete_wishlist parameter
Database error messages returned to authenticated customer sessions
Unexpected SELECT, UNION, or INFORMATION_SCHEMA queries in database logs originating from the web application user
Sudden spikes in wishlist-related requests from a single authenticated account

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the delete_wishlist parameter for SQL injection payloads
Enable database query logging and alert on syntactically anomalous queries produced by my_account.php
Correlate authenticated session activity with database errors to surface probing attempts

Monitoring Recommendations

Monitor HTTP access logs for repeated 500-series responses tied to the wishlist endpoint
Track outbound data volumes from the ecommerce database to detect bulk extraction
Review authentication logs for newly created customer accounts followed by immediate wishlist activity

How to Mitigate CVE-2026-14799

Immediate Actions Required

Restrict access to /customer/my_account.php?my_wishlist behind a WAF with SQL injection signatures enabled
Audit the delete_wishlist code path and replace string concatenation with parameterized queries
Rotate database credentials if logs indicate prior exploitation attempts
Review customer account creation controls to slow automated attacker registration

Patch Information

No official vendor patch is referenced in the advisory data. Administrators should consult CodeAstro Security Resources for updated releases and monitor the VulDB Vulnerability #376393 entry for remediation status.

Workarounds

Apply virtual patching at the WAF layer to block SQL metacharacters in the delete_wishlist parameter
Enforce least-privilege database accounts so the web application cannot read sensitive tables beyond its scope
Disable the wishlist feature temporarily if it is not business-critical
Implement input allowlisting to accept only numeric identifiers for wishlist item deletion

bash
