CVE-2026-24913 Overview
A SQL Injection vulnerability exists in MATCHA INVOICE version 2.6.6 and earlier. If this vulnerability is exploited, information stored in the database may be obtained or altered by an authenticated user who can log in to the product. This vulnerability (CWE-89) allows attackers with valid credentials to manipulate database queries, potentially leading to unauthorized data access or modification.
Critical Impact
Authenticated attackers can exploit SQL Injection to read or modify sensitive invoice and business data stored in the application database, potentially compromising financial records and customer information.
Affected Products
- MATCHA INVOICE version 2.6.6
- MATCHA INVOICE versions prior to 2.6.6

Technical Details for CVE-2026-24913
Vulnerability Analysis
This SQL Injection vulnerability (CWE-89) in MATCHA INVOICE allows authenticated users to inject malicious SQL statements into application queries. The vulnerability requires network access and authenticated credentials to exploit, but once authenticated, an attacker can manipulate SQL queries to extract sensitive database contents or modify existing records.
The attack does not require user interaction and can be executed remotely over the network. Successful exploitation could result in complete compromise of the database confidentiality and integrity, affecting all stored invoice data, customer information, and financial records managed by the application.
Root Cause
The root cause of this vulnerability is improper neutralization of special elements used in SQL commands (SQL Injection). The application fails to properly sanitize or parameterize user-controlled input before incorporating it into SQL queries. This allows authenticated users to inject arbitrary SQL syntax that gets executed by the database engine with the application's privileges.
Attack Vector
The vulnerability is exploitable over the network by authenticated users. An attacker with valid login credentials can craft malicious input containing SQL metacharacters and statements. When the application processes this input without proper validation, the injected SQL code executes against the backend database.
Typical attack scenarios include:
- Using UNION-based injection to extract data from other database tables
- Employing boolean-based blind injection to enumerate database contents character by character
- Leveraging time-based blind injection techniques to infer data when direct output is not available
- Executing INSERT, UPDATE, or DELETE statements to modify or destroy database records
Since no verified code examples are available for this vulnerability, technical details can be found in the JVN #33581068 Advisory and the ICZ Security News Update.
Detection Methods for CVE-2026-24913
Indicators of Compromise
- Unusual database query patterns in application logs containing SQL metacharacters such as single quotes, semicolons, or UNION statements
- Authentication logs showing legitimate user accounts accessing abnormal amounts of data or unusual database tables
- Database audit logs revealing queries with unexpected syntax or accessing tables outside normal application scope
- Web application firewall logs detecting SQL injection patterns in request parameters
Detection Strategies
- Deploy web application firewall (WAF) rules to detect and block common SQL injection patterns in HTTP requests
- Enable database query logging and monitor for anomalous SQL statements containing injection indicators
- Implement application-level logging to track user input and correlate with database activity
- Configure SentinelOne to monitor for process behavior consistent with SQL injection exploitation
Monitoring Recommendations
- Enable verbose logging on the MATCHA INVOICE application to capture all user inputs and database interactions
- Monitor database connections for unusual query volumes or data extraction patterns from authenticated sessions
- Set up alerts for database error messages that may indicate failed injection attempts
- Review audit logs regularly for signs of data exfiltration or unauthorized database modifications
How to Mitigate CVE-2026-24913
Immediate Actions Required
- Upgrade MATCHA INVOICE to a patched version newer than 2.6.6 when available from the vendor
- Restrict network access to the MATCHA INVOICE application to trusted networks and users only
- Review and audit all user accounts with access to the application, removing any unnecessary privileges
- Implement additional input validation at the web application firewall level as a defense-in-depth measure
Patch Information
Refer to the vendor's official security advisory for patch availability and installation instructions. The ICZ Security News Update contains vendor-provided remediation guidance. Additionally, the JVN #33581068 Advisory provides coordinated vulnerability disclosure details.
Organizations should prioritize patching this vulnerability given its network-accessible attack surface and the potential for authenticated users to compromise database confidentiality and integrity.
Workarounds
- Implement strict input validation at the application perimeter using a web application firewall with SQL injection detection rules enabled
- Limit database user permissions to the minimum required privileges, preventing the application database account from accessing system tables or executing administrative commands
- Enable database auditing to detect and alert on suspicious query patterns
- Consider network segmentation to isolate the MATCHA INVOICE application from other critical systems
# Example WAF configuration to block common SQL injection patterns
# Consult your WAF vendor documentation for specific implementation
# Block requests containing common SQL injection metacharacters
# Monitor and log blocked requests for incident response
