CVE-2026-14654: Remote SQL Injection in SourceCodester Simple and Nice Shopping Cart Script

A critical SQL injection vulnerability, identified as CVE-2026-14654, has been discovered in version 1.0 of the SourceCodester Simple and Nice Shopping Cart Script. This flaw specifically affects an unknown function within the /admin/girlsproductdeletequery.php file, where improper neutralization of special elements in the user_id argument leads to SQL injection. The vulnerability allows a remote and unauthenticated attacker to inject malicious SQL commands into database queries. The exploit for this vulnerability is publicly available, increasing the likelihood of its use in the wild. This poses a significant risk to organizations utilizing the affected software, enabling potential unauthorized access, data manipulation, or even remote code execution if the underlying database user has elevated privileges. The vulnerability was published on July 4, 2026.

Attack Chain

1. An attacker identifies an internet-facing instance of SourceCodester Simple and Nice Shopping Cart Script 1.0.
2. The attacker crafts a malicious HTTP GET or POST request to the /admin/girlsproductdeletequery.php endpoint.
3. The request includes specially constructed SQL injection payloads within the user_id parameter, such as ' OR 1=1-- or UNION SELECT ....
4. The vulnerable application processes the user_id argument without adequate sanitization, causing the injected SQL commands to be executed by the backend database.
5. Successful injection allows the attacker to bypass authentication, query sensitive database information (e.g., user credentials, product details), modify existing data, or delete records.
6. Depending on the database system and the privileges of the database user account, the attacker may escalate the SQL injection to achieve remote code execution (RCE) on the underlying web server.
7. If RCE is successful, the attacker can establish persistent access mechanisms, such as deploying web shells or other backdoors.
8. The final objective often includes data exfiltration, website defacement, or broader compromise of the hosting infrastructure.

Impact

Successful exploitation of CVE-2026-14654 can lead to severe consequences for affected organizations. Attackers can gain unauthorized access to the application's database, allowing for the theft of sensitive customer and product information, modification of order details, or deletion of critical data. While specific victim counts or targeted sectors are not available, any organization using SourceCodester Simple and Nice Shopping Cart Script 1.0 is at risk. The publicly available exploit further exacerbates the threat, making it easier for malicious actors to compromise systems and disrupt business operations.
