The vulnerability CVE-2026-4841 affects the code-projects Online Food Ordering System version 1.0, specifically within the Shopping Cart Module's form/cart.php file. The issue stems from insufficient input validation and sanitization of the 'del' parameter, which is used to manipulate the shopping cart contents. An attacker can remotely send crafted requests to this parameter, injecting malicious SQL code that the backend database executes. This SQL Injection flaw allows attackers to read, modify, or delete data within the database, potentially exposing sensitive customer information, altering order details, or disrupting service availability. The vulnerability requires no authentication or user interaction, making it highly accessible to remote attackers. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no active exploitation has been reported, the availability of a public exploit increases the likelihood of future attacks. The lack of official patches or updates at the time of publication necessitates immediate mitigation efforts by affected organizations.

If exploited, this SQL Injection vulnerability can lead to unauthorized disclosure of sensitive customer data such as personal details and order history, compromising confidentiality. Attackers may also alter or delete order records, impacting data integrity and potentially causing financial losses or operational disruptions. Availability could be affected if attackers execute destructive queries or cause database errors, leading to denial of service for legitimate users. Given the remote and unauthenticated nature of the exploit, the threat is significant for organizations relying on this software for online food ordering, especially those handling large volumes of customer transactions. The presence of a public exploit increases the risk of automated or opportunistic attacks, potentially affecting customer trust and regulatory compliance.

Since no official patches are currently available, organizations should implement immediate mitigations including: 1) Applying strict input validation and sanitization on the 'del' parameter to ensure only expected values are processed. 2) Employing parameterized queries or prepared statements in the database access code to prevent injection. 3) Restricting database user permissions to the minimum necessary to limit damage from potential exploits. 4) Monitoring web server and database logs for suspicious activities targeting the 'del' parameter or unusual query patterns. 5) Using Web Application Firewalls (WAFs) with rules to detect and block SQL Injection attempts targeting this endpoint. 6) Considering temporary disabling or restricting access to the vulnerable Shopping Cart Module if feasible until a patch is released. 7) Planning for prompt application of official patches or updates once available from the vendor. 8) Conducting security audits and code reviews of the affected module to identify and remediate similar vulnerabilities.
