CVE-2026-14653 Overview
CVE-2026-14653 is a SQL injection vulnerability in SourceCodester Simple and Nice Shopping Cart Script 1.0. The flaw resides in the /admin/mensproductdeletequery.php script, where the user_id parameter is passed to a database query without proper sanitization. Remote attackers can manipulate the parameter to inject arbitrary SQL statements. The exploit has been publicly disclosed and may be used against unpatched deployments. The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component).
Critical Impact
Remote, unauthenticated attackers can inject SQL into the administrative product deletion endpoint, allowing manipulation of backend database contents used by the shopping cart application.
Affected Products

Technical Details for CVE-2026-14653
Vulnerability Analysis
The vulnerability exists in the administrative product deletion workflow of Simple and Nice Shopping Cart Script 1.0. The mensproductdeletequery.php script accepts a user_id request parameter and concatenates it directly into a SQL statement executed against the backend database. Because the input is neither parameterized nor escaped, an attacker can append arbitrary SQL clauses to the query. Successful exploitation allows reading, modifying, or deleting rows outside the intended scope of the delete operation. The advisory notes that exploitation requires no authentication and is reachable across the network.
Root Cause
The root cause is improper neutralization of special elements passed through the user_id parameter [CWE-74]. The application constructs its SQL query using unsanitized user input, allowing attacker-controlled data to break out of the intended query context. This is a canonical string-concatenation SQL injection pattern where prepared statements or parameter binding were not used.
Attack Vector
An attacker sends a crafted HTTP request to /admin/mensproductdeletequery.php with a malicious user_id value. The injected payload can terminate the original query and append additional statements or subqueries. Because the endpoint is exposed to the network and does not require valid credentials in the vulnerable configuration, exploitation can be automated. Public disclosure of the exploit increases the likelihood of opportunistic scanning against internet-facing installations.

Detection Methods for CVE-2026-14653
Indicators of Compromise
- Web server access logs containing requests to /admin/mensproductdeletequery.php with user_id values including SQL metacharacters such as ', --, UNION, SELECT, or SLEEP(.
- Unusually long or URL-encoded user_id query strings originating from a small set of source IP addresses.
- Unexpected DELETE, UPDATE, or SELECT statements appearing in database query logs correlated with requests to the admin endpoint.
- Missing, altered, or duplicated rows in product and user tables that cannot be tied to legitimate administrative activity.
Detection Strategies
- Deploy a Web Application Firewall (WAF) signature that inspects the user_id parameter on the admin path for SQL injection patterns and blocks non-numeric input.
- Enable database query logging and alert on syntax errors returned by MySQL/MariaDB when queries originate from the shopping cart application user.
- Correlate HTTP 500 responses from /admin/* endpoints with database error messages to surface probing activity.
Monitoring Recommendations
- Monitor authentication and authorization events on the /admin/ directory and alert on access from unexpected geographies or user agents.
- Track outbound connections from the web server host to detect data exfiltration attempts following successful injection.
- Baseline normal admin traffic volume and alert on spikes to product management endpoints.
How to Mitigate CVE-2026-14653
Immediate Actions Required
- Restrict network access to the /admin/ directory using IP allow-lists, VPN, or reverse-proxy authentication until a code fix is applied.
- Replace the vulnerable SQL statement in mensproductdeletequery.php with a parameterized query or prepared statement using PDO or mysqli bound parameters.
- Validate that the user_id parameter is a strictly numeric integer before it reaches any database call.
- Review database and application logs for prior exploitation attempts and rotate administrative credentials if compromise is suspected.
Patch Information
No official vendor patch is referenced in the advisory for CVE-2026-14653. Organizations running Simple and Nice Shopping Cart Script 1.0 should apply the source code changes described in the VulDB CVE Record or discontinue use of the affected script. Monitor the SourceCodester Security Resource for any future release addressing the flaw.
Workarounds
- Place the application behind a WAF configured with SQL injection rule sets and enforce strict parameter typing on user_id.
- Apply the principle of least privilege to the database account used by the application so that only DELETE on the specific product tables is permitted.
- If administrative product deletion is not actively required, remove or rename mensproductdeletequery.php to eliminate the attack surface.
