CVE-2026-1050: Risesoft-y9 Digital Infrastructure SQLi

CVE-2026-1050 Overview

A SQL injection vulnerability has been identified in risesoft-y9 Digital-Infrastructure versions up to 9.6.7. The flaw exists in an unknown function within the file source-code/src/main/java/net/risesoft/util/Y9PlatformUtil.java, which is part of the REST Authenticate Endpoint component. Attackers can exploit this vulnerability remotely by manipulating input parameters to inject malicious SQL queries, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

This SQL injection vulnerability in the REST Authenticate Endpoint can be exploited remotely without authentication, potentially allowing attackers to bypass authentication mechanisms, extract sensitive data, or manipulate the underlying database.

Affected Products

• risesoft-y9 Digital-Infrastructure up to version 9.6.7
• REST Authenticate Endpoint component
• Y9PlatformUtil.java utility class

Technical Details for CVE-2026-1050

Vulnerability Analysis

The vulnerability resides in the Y9PlatformUtil.java file within the risesoft-y9 Digital-Infrastructure platform. This utility class handles operations for the REST Authenticate Endpoint, and the flaw stems from improper handling of user-supplied input before it is incorporated into SQL queries. The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws including SQL injection.

The attack can be initiated remotely over the network without requiring any special privileges or user interaction. An exploit for this vulnerability has been publicly disclosed, and the project maintainers were notified through an issue report but have not yet responded to the disclosure.

Root Cause

The root cause of this vulnerability is the improper sanitization or parameterization of user-controlled input before it is used in SQL query construction within the Y9PlatformUtil.java utility class. When input from the REST Authenticate Endpoint is directly concatenated into SQL statements without proper validation or the use of prepared statements, attackers can inject arbitrary SQL code.

Attack Vector

The vulnerability can be exploited remotely via network-based attacks targeting the REST Authenticate Endpoint. An attacker can craft malicious HTTP requests containing SQL injection payloads in authentication parameters. Since no authentication or user interaction is required for exploitation, this presents a significant risk for systems exposed to untrusted networks.

The attack mechanism involves sending specially crafted input to the affected endpoint, where the malicious SQL payload is processed by the Y9PlatformUtil.java class and executed against the backend database. For detailed technical information about the exploitation method, refer to the GitHub Issue Discussion where the vulnerability was originally reported.

Detection Methods for CVE-2026-1050

Indicators of Compromise

• Unusual SQL error messages or database exceptions in application logs related to the REST Authenticate Endpoint
• Unexpected database queries containing SQL syntax characters such as single quotes, semicolons, or UNION statements
• Authentication bypass events or unauthorized access to protected resources
• Anomalous network traffic patterns to the REST authentication endpoints

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting authentication endpoints
• Implement database activity monitoring to identify suspicious query patterns, especially those containing injection signatures
• Review application logs for authentication-related errors that may indicate exploitation attempts
• Configure intrusion detection systems (IDS) to alert on SQL injection attack patterns in HTTP traffic

Monitoring Recommendations

• Enable verbose logging for the REST Authenticate Endpoint and monitor for SQL-related exceptions
• Set up alerts for failed authentication attempts combined with database errors
• Monitor database query logs for unusual patterns such as UNION-based queries, time-based delays, or stacked queries
• Track access to the Y9PlatformUtil.java related endpoints for anomalous request volumes or patterns

How to Mitigate CVE-2026-1050

Immediate Actions Required

• Restrict network access to the REST Authenticate Endpoint to trusted IP addresses only
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules in front of the affected application
• Review and audit all authentication-related code paths for proper input validation
• Consider temporarily disabling the affected endpoint if it is not business-critical until a patch is available

Patch Information

As of the last update on 2026-01-17, the risesoft-y9 project maintainers have not responded to the vulnerability disclosure submitted via GitHub Issue. Organizations using affected versions should monitor the project repository for security updates and consider implementing workarounds until an official patch is released. Additional vulnerability details are available through VulDB #341603.

Workarounds

• Implement input validation and sanitization at the application level for all parameters reaching the REST Authenticate Endpoint
• Use parameterized queries or prepared statements if modifying the source code directly
• Deploy network-level controls such as WAF rules and rate limiting to reduce exposure
• Apply the principle of least privilege to database accounts used by the application to minimize potential damage from successful exploitation

# Example WAF rule configuration to block common SQL injection patterns
# ModSecurity rule example
SecRule ARGS "@detectSQLi" "id:1001,phase:2,deny,status:403,msg:'SQL Injection Detected',log,auditlog"

# Restrict access to authentication endpoints (nginx example)
location /api/authenticate {
    allow 10.0.0.0/8;
    allow 192.168.0.0/16;
    deny all;
