CVE-2025-7187 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Chat System, specifically within an unspecified function in the /user/fetch_member.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which can be manipulated by an attacker to inject malicious SQL code. This injection flaw allows an attacker to remotely execute arbitrary SQL commands against the backend database without requiring authentication or user interaction. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no confirmed exploits have been observed in the wild to date. The CVSS 4.0 base score is 5.3, indicating a medium severity level, reflecting factors such as network attack vector, low complexity, no privileges or user interaction required, but limited impact on confidentiality, integrity, and availability. The vulnerability could potentially allow attackers to extract sensitive data, modify database contents, or disrupt service availability depending on the database permissions and structure. However, the impact is rated as limited due to the vulnerability's partial impact on confidentiality, integrity, and availability. The lack of available patches or official remediation guidance increases the urgency for organizations to implement compensating controls or mitigations.

For European organizations using the code-projects Chat System version 1.0, this vulnerability poses a risk of unauthorized data access and potential data manipulation. Given the chat system likely handles user communication data, exploitation could lead to exposure of personal or sensitive information, violating GDPR and other data protection regulations. The ability to execute SQL commands remotely without authentication increases the threat surface, potentially allowing attackers to compromise user privacy and trust. Additionally, data integrity could be affected if attackers modify chat records or user information, impacting operational reliability. Availability impact is limited but possible if attackers execute commands that disrupt database operations. The medium severity rating suggests that while the threat is significant, the overall risk depends on the deployment context, database permissions, and existing security controls. European organizations must consider the regulatory implications of data breaches and the reputational damage associated with compromised communication platforms.

Since no official patches are currently available, European organizations should immediately audit and restrict access to the affected chat system, especially limiting exposure of the /user/fetch_member.php endpoint. Implementing Web Application Firewalls (WAFs) with SQL Injection detection and prevention rules can help block malicious payloads targeting the 'ID' parameter. Input validation and sanitization should be enforced at the application level, ideally by updating or rewriting the vulnerable code to use parameterized queries or prepared statements to prevent injection. Organizations should monitor logs for suspicious activity related to the vulnerable endpoint and consider isolating the chat system database with least privilege principles to minimize potential damage. Regular backups of the database should be maintained to enable recovery in case of data tampering. Finally, organizations should track vendor communications for any forthcoming patches and plan timely updates once available.
