CVE-2025-12299 is a cross-site scripting vulnerability identified in the Simple Food Ordering System version 1.0 developed by code-projects. The vulnerability resides in the /addproduct.php script, where the parameters pname, category, and price are not properly sanitized or validated, allowing attackers to inject malicious JavaScript code. This flaw enables remote attackers to craft URLs or requests that, when visited or processed by a victim's browser, execute arbitrary scripts in the context of the vulnerable web application. The vulnerability requires no authentication and can be exploited remotely, but user interaction is necessary for the attack to succeed (e.g., clicking a malicious link). The CVSS 4.0 vector indicates low attack complexity and no privileges required, but user interaction is needed. The impact primarily affects confidentiality and integrity by enabling session hijacking, credential theft, or manipulation of displayed content. Although no patches or fixes have been officially released yet, the public availability of exploit code increases the urgency for mitigation. The vulnerability is particularly relevant for organizations running this software in production environments, especially those handling customer data or payment information. Proper input validation, output encoding, and use of security headers are critical to mitigating this threat.

For European organizations, especially those in the hospitality and food service sectors using the Simple Food Ordering System, this vulnerability could lead to significant security incidents. Successful exploitation could result in theft of customer credentials, unauthorized access to user sessions, and potential defacement or manipulation of the ordering interface, undermining customer trust and business reputation. Additionally, attackers could use the vulnerability as a foothold for further attacks such as phishing or spreading malware. Given the public availability of exploit code, the risk of targeted attacks is elevated. The impact on data privacy is particularly concerning under the GDPR framework, as compromised customer data could lead to regulatory penalties and legal liabilities. Organizations relying on this software without timely mitigation may face service disruptions and financial losses due to fraud or remediation costs.

To mitigate CVE-2025-12299, organizations should immediately implement strict input validation and output encoding on the pname, category, and price parameters within /addproduct.php. Employing a whitelist approach for acceptable input values can significantly reduce injection risks. Utilizing security libraries or frameworks that automatically handle XSS protections is recommended. Web Application Firewalls (WAFs) can be configured to detect and block suspicious input patterns targeting these parameters. Monitoring web server logs for unusual requests to /addproduct.php can help identify attempted exploits. Since no official patch is currently available, organizations should consider isolating or restricting access to the affected application until a fix is released. Educating staff and users about the risks of clicking unknown links can reduce successful exploitation. Finally, applying Content Security Policy (CSP) headers can limit the impact of injected scripts by restricting script execution sources.
