CVE-2026-14653: SQL Injection in SourceCodester Shopping Cart 1.0 – Remote Code Execution Risk

Technical summary

CVE-2026-14653 is a remote SQL injection flaw in SourceCodester Simple and Nice Shopping Cart Script 1.0. The vulnerable endpoint /admin/mensproductdeletequery.php fails to properly sanitize or parameterize the user_id input parameter before incorporating it into SQL queries. This classic improper input validation issue (CWE-74, CWE-89) allows unauthenticated network attackers to execute arbitrary SQL statements against the underlying database. The attack vector requires no special privileges, no user interaction, and no changes to the system's security configuration, making it straightforward to exploit.

Business impact

Organizations running SourceCodester Simple and Nice Shopping Cart Script 1.0 face immediate risk of unauthorized database access and manipulation. Attackers can exfiltrate customer data (names, email addresses, purchase history), modify product inventory, manipulate pricing, or delete transactional records. For e-commerce operations, this translates to data breach liability, customer trust erosion, regulatory penalties under data protection laws, and potential business interruption. The public availability of exploit code means threat actors will likely begin targeting this vulnerability in the near term.

Affected systems

SourceCodester Simple and Nice Shopping Cart Script version 1.0 is vulnerable. Organizations should audit their environments to identify instances of this application, particularly those exposed to untrusted networks or the public internet. Verify the exact version running and determine whether the admin panel is accessible from external sources.

Exploitability

Exploitability is high. The vulnerability requires no authentication, no special user interaction, and no system configuration changes. Network access to the vulnerable endpoint is the only prerequisite. Public exploit code has been disclosed, meaning attack tooling and proof-of-concept demonstrations are available to threat actors. Any delay in patching increases the window of opportunity for active exploitation.

Remediation

Verify and apply any available security patches from SourceCodester for version 1.0. If patches are unavailable or the vendor is unresponsive, prioritize isolating the admin panel from public internet access using network segmentation, IP whitelisting, or Web Application Firewalls that can detect and block SQL injection attempts. Consider migrating to an alternative, actively maintained shopping cart platform if vendor support has ended.

Patch guidance

Contact SourceCodester directly or monitor their official channels for security updates addressing this vulnerability. Verify the specific patch version against the vendor's advisory before deployment. If running this application in production, establish a testing environment to validate patches before rolling out to live systems. Document all patching activities and affected systems for compliance and incident response records.

Detection guidance

Monitor access logs for /admin/mensproductdeletequery.php and watch for suspicious patterns in the user_id parameter—specifically, SQL keywords (SELECT, UNION, OR, --), encoded payloads (URL encoding, hex notation), or unusual character sequences. Implement Web Application Firewall rules to block common SQL injection patterns. Enable database query logging to identify anomalous SQL statements. Security Information and Event Management (SIEM) systems should correlate failed and successful database queries with web request logs to detect post-exploitation activity.

Why prioritize this

This vulnerability merits immediate remediation attention despite not being on CISA's Known Exploited Vulnerabilities list. The combination of high CVSS score (7.3), publicly available exploits, zero authentication requirements, and remote network exploitability creates substantial active threat. SQL injection attacks on e-commerce platforms directly compromise customer data and business operations. Any instance of this application exposed to untrusted networks should be treated as a critical priority.

Risk score, explained

The CVSS 3.1 score of 7.3 (HIGH) reflects the vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L, indicating network-based attack with low complexity, no privileges required, no user interaction, with impacts to confidentiality, integrity, and availability. The score is justified by the combination of ease of exploitation and multi-faceted business impact. The public disclosure of exploits and absence of KEV status should not be mistaken as lower risk—the vulnerability remains actively exploitable and should be treated with urgency proportional to your environment's exposure.
