Compliance Impact

The SQL Injection vulnerability (CVE-2026-24913) in MATCHA INVOICE 2.6.6 and earlier allows an authenticated user with low privileges to obtain or alter information stored in the database. This unauthorized access or modification of sensitive data can lead to violations of data protection regulations such as GDPR and HIPAA, which require the protection of confidentiality, integrity, and availability of personal and sensitive information.

Because the vulnerability impacts confidentiality, integrity, and availability of data, it poses a significant risk to compliance with standards that mandate strict controls over data access and protection, potentially resulting in legal and regulatory consequences if exploited.

Mitigation by updating to the fixed version (MATCHA INVOICE 2.6.7) is recommended to restore compliance and reduce risk.

Detection Guidance

The vulnerability CVE-2026-24913 is an SQL Injection in MATCHA INVOICE 2.6.6 and earlier versions, exploitable by authenticated users. Detection typically involves testing for SQL injection points in the application, especially parameters such as params[sort] that are known to be vulnerable.

To detect this vulnerability on your system, you can perform authenticated SQL injection testing by sending crafted requests to the application and observing if database errors or unexpected data responses occur.

• Use tools like sqlmap with authentication cookies or credentials to test injection points, for example: sqlmap -u "http://target/matcha_invoice" --data="params[sort]=1" --cookie="session=your_session_cookie" --risk=3 --level=5
• Manually test the vulnerable parameter by injecting SQL syntax such as a single quote (') or SQL keywords into params[sort] and observe if errors or abnormal behavior occur.
• Monitor web server logs for suspicious requests containing SQL keywords or unusual parameter values targeting params[sort].

Since the vulnerability requires authentication, ensure you have valid credentials to perform these tests safely.
