CVE-2025-7188 is a SQL Injection vulnerability identified in version 1.0 of the code-projects Chat System, specifically within the /user/addmember.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which is susceptible to malicious input manipulation. An attacker can exploit this flaw remotely without requiring user interaction or authentication, allowing them to inject arbitrary SQL commands into the backend database queries. This can lead to unauthorized data access, modification, or deletion, potentially compromising the confidentiality, integrity, and availability of the application’s data. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits are currently reported in the wild. The CVSS v4.0 score is 5.3 (medium severity), reflecting the moderate impact and ease of exploitation with limited privileges required. The vulnerability does not require user interaction but does require low privileges (PR:L), indicating that some level of access to the system is necessary to exploit it. The vulnerability affects only version 1.0 of the Chat System, which may limit the scope depending on the deployment of this specific version.

For European organizations using the code-projects Chat System 1.0, this vulnerability poses a significant risk to sensitive communication data and user information managed within the chat platform. Exploitation could lead to unauthorized disclosure of confidential conversations, user credentials, or other sensitive data stored in the backend database. Additionally, attackers could manipulate or delete data, disrupting communication workflows and potentially causing operational downtime. Given the remote exploitability and lack of user interaction required, attackers could automate attacks to compromise multiple systems rapidly. This risk is particularly acute for organizations in sectors with stringent data protection requirements such as finance, healthcare, and government institutions within Europe, where breaches could lead to regulatory penalties under GDPR and damage to reputation. However, the medium severity rating and requirement for low privileges may reduce the likelihood of widespread exploitation unless attackers gain initial access to the system.

To mitigate this vulnerability effectively, European organizations should prioritize upgrading or patching the code-projects Chat System to a version where this issue is resolved, if available. In the absence of an official patch, organizations should implement strict input validation and parameterized queries or prepared statements in the /user/addmember.php functionality to prevent SQL injection. Employing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'ID' parameter can provide an additional layer of defense. Regular security audits and code reviews focusing on input handling should be conducted to identify similar vulnerabilities. Network segmentation and least privilege principles should be enforced to limit the ability of attackers to gain the required low privilege level to exploit this vulnerability. Monitoring and logging database queries and application logs for suspicious activity related to the 'ID' parameter can aid in early detection of exploitation attempts. Lastly, educating developers and administrators about secure coding practices and timely vulnerability management is crucial.
