CVE-2025-9749 is a SQL Injection vulnerability identified in the HKritesh009 Grocery List Management Web App, specifically affecting the /src/update.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which can be manipulated remotely by an attacker to inject malicious SQL code. This injection flaw allows attackers to interfere with the application's database queries, potentially leading to unauthorized data access, data modification, or deletion. The vulnerability is exploitable without authentication or user interaction, increasing its risk profile. The product follows a rolling release model, which complicates pinpointing exact affected versions or patches. The CVSS 4.0 score of 6.9 (medium severity) reflects a network-exploitable vulnerability with low impact on confidentiality, integrity, and availability individually, but combined they could lead to significant data exposure or corruption. Although no known exploits are currently in the wild, public exploit code is available, increasing the likelihood of exploitation. The vulnerability affects a web application used for grocery list management, which may be deployed in small to medium business environments or personal use cases. The lack of authentication requirement and remote exploitability make this a notable threat vector for attackers aiming to compromise backend databases or pivot within affected networks.

For European organizations, the impact of CVE-2025-9749 depends largely on the deployment scale and sensitivity of data managed by the Grocery List Management Web App. While the app itself may not be widely used in large enterprises, smaller businesses or startups in the food retail or supply chain sectors could be affected. Exploitation could lead to unauthorized access to user data, manipulation of grocery lists, or disruption of service availability. In regulated environments, such as those governed by GDPR, unauthorized data access could result in compliance violations and financial penalties. Additionally, attackers could leverage this vulnerability as an initial foothold to conduct further attacks within a network, potentially escalating privileges or exfiltrating sensitive information. The remote and unauthenticated nature of the exploit increases the risk of widespread automated attacks, especially if the app is publicly accessible. European organizations relying on this software should be aware of the potential for data integrity issues and reputational damage stemming from successful exploitation.

To mitigate CVE-2025-9749, organizations should immediately review and sanitize all inputs, especially the 'ID' parameter in /src/update.php, using parameterized queries or prepared statements to prevent SQL injection. Since the product uses a rolling release model without clear patch versions, organizations should monitor the vendor's repository or communication channels for updates or fixes addressing this vulnerability. In the interim, deploying Web Application Firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the affected endpoint can reduce exposure. Conducting thorough code reviews and penetration testing focused on injection flaws is recommended. Additionally, restricting public access to the application or segmenting it within a secure network zone can limit attack surface. Logging and monitoring database queries for anomalous patterns may help in early detection of exploitation attempts. Finally, educating developers and administrators about secure coding practices and input validation is critical to prevent similar vulnerabilities.
