CVE-2026-14654 Overview
CVE-2026-14654 is a SQL injection vulnerability in SourceCodester Simple and Nice Shopping Cart Script 1.0. The flaw resides in the /admin/girlsproductdeletequery.php script, where the user_id parameter is passed to a database query without proper sanitization. Attackers can manipulate this parameter to inject arbitrary SQL statements. The vulnerability is remotely exploitable, requires no authentication, and no user interaction. A public exploit reference exists via the vendor's GitHub issue tracker, increasing the likelihood of opportunistic attacks against exposed installations.
Critical Impact
Unauthenticated remote attackers can inject SQL through the user_id parameter of an administrative endpoint, potentially exposing or modifying data in the backend database.
Affected Products
- SourceCodester Simple and Nice Shopping Cart Script 1.0
- Component: /admin/girlsproductdeletequery.php
- Vulnerable parameter: user_id

Technical Details for CVE-2026-14654
Vulnerability Analysis
The vulnerability is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The affected script, /admin/girlsproductdeletequery.php, processes a user_id argument supplied by the client and concatenates it into a SQL statement executed against the backend database. Because the value is not parameterized or sanitized, attackers can break out of the intended query context and append arbitrary SQL clauses.
Exploitation requires only a crafted HTTP request to the affected endpoint. According to the published advisory, no privileges are required and the attack can be executed over the network, which places any internet-facing deployment at risk. The EPSS probability at time of publication is 0.412%.
Root Cause
The root cause is direct interpolation of user-controlled input into a SQL statement inside girlsproductdeletequery.php. The script fails to use prepared statements or input validation for the user_id parameter, allowing an attacker to alter query semantics. This is a common defect pattern in PHP applications that build queries through string concatenation with values sourced from $_GET or $_POST superglobals.
Attack Vector
An attacker sends an HTTP request to /admin/girlsproductdeletequery.php with a malicious user_id value. Because the endpoint sits under /admin/ but appears to lack enforced authentication in the affected build, exploitation does not require valid credentials. Successful injection can enable data extraction using UNION-based or boolean-based techniques, tampering with product and user records, or authentication bypass through query manipulation. Refer to the GitHub Issue Report and VulDB Vulnerability Report for technical details.
Detection Methods for CVE-2026-14654
Indicators of Compromise
- HTTP requests to /admin/girlsproductdeletequery.php containing SQL metacharacters such as ', --, UNION, SELECT, or SLEEP( within the user_id parameter.
- Web server access logs showing repeated requests to the affected endpoint from a single source with varying user_id payloads.
- Unexpected database error messages returned to clients or logged by the PHP application.
- Unexplained changes to product or user tables in the shopping cart database.
Detection Strategies
- Deploy web application firewall (WAF) signatures that flag SQL injection patterns targeting the user_id parameter on the girlsproductdeletequery.php path.
- Enable MySQL general query logging or slow query logging temporarily to identify malformed queries originating from the affected script.
- Correlate outbound data volumes from the web server with incoming requests to /admin/ endpoints to detect data exfiltration attempts.
Monitoring Recommendations
- Alert on any HTTP 500 responses from /admin/girlsproductdeletequery.php, which often accompany SQL syntax errors during injection probing.
- Monitor for repeated requests to the admin directory from unauthenticated sessions or foreign geolocations.
- Track database user activity for the account used by the web application, looking for INFORMATION_SCHEMA reads or bulk SELECT statements.
How to Mitigate CVE-2026-14654
Immediate Actions Required
- Restrict network access to /admin/ paths using IP allow-lists at the web server or reverse proxy layer until a patched build is available.
- Deploy WAF rules that block SQL injection payloads in the user_id parameter of girlsproductdeletequery.php.
- Rotate database credentials used by the application and review recent database logs for signs of exploitation.
- Take the application offline if it is internet-exposed and handles sensitive customer data.
Patch Information
No official vendor patch has been referenced in the NVD entry at the time of publication. Administrators should monitor the SourceCodester Blog and the VulDB CVE-2026-14654 record for updated fix information. Where source code access is available, remediate by replacing string-concatenated SQL with parameterized queries using PDO or MySQLi prepared statements, and enforce integer casting on user_id.
Workarounds
- Add authentication and session checks to girlsproductdeletequery.php so unauthenticated visitors cannot reach the vulnerable code path.
- Apply strict server-side input validation to force user_id to an integer before use, for example via (int)$_REQUEST['user_id'].
- Grant the database account used by the application only the minimum privileges required, removing DROP, ALTER, and cross-database SELECT rights.
- Consider migrating to a maintained e-commerce platform if the vendor does not issue a patch.
