YS-infoware BA-Workflow SQL Injection Risks Database Integrity

YS-infoware BA-Workflow versions prior to 3.6 contain a SQL injection vulnerability. Authenticated remote attackers can exploit this flaw to execute arbitrary SQL statements, enabling them to read, modify, or delete sensitive data stored within the application.

What happened

The National Vulnerability Database recorded CVE-2026-113406 to track this security issue in YS-infoware BA-Workflow. The vulnerability is classified under CWE-89, which denotes SQL injection weaknesses in software architecture. According to the advisory, the flaw affects YS-infoware BA-Workflow before version 3.6. This means deployments running versions earlier than 3.6 are subject to the defect.

The technical description states that an attacker must first authenticate to the system to trigger the injection. Once logged in, the threat actor can inject arbitrary SQL commands into the application’s input fields. These commands interact directly with the underlying database engine. The result is the ability to read, modify, and delete database contents.

Why it matters

The Common Vulnerability Scoring System assigns this flaw a base score of 8.7, placing it in the high severity category. This rating reflects the potential for data loss and unauthorized modification. Because the attack requires authentication, the risk is focused on compromised user accounts or stolen credentials. However, the impact on the database is significant, allowing full read, write, and delete capabilities.

Organisations using BA-Workflow for business process management face risk to their operational data. The high CVSS score indicates the vulnerability has a substantial impact on confidentiality and integrity. Security teams must treat this as a priority remediation task. The source material does not specify whether the flaw is currently being exploited in the wild.

What happens next

• Identify all instances of YS-infoware BA-Workflow currently in use.
• Verify the installed version against the 3.6 threshold.
• Plan an immediate upgrade path for any systems running older builds.
• Monitor logs for unusual database queries from authenticated users.

Patch priority

Teams should prioritise systems with the highest exposure to external networks or those handling sensitive data. Begin by isolating vulnerable instances from untrusted networks if immediate patching is not feasible. Test the upgrade to version 3.6 in a staging environment to ensure compatibility with existing workflows. Back up all database contents before applying any changes. Roll out the fix in phases, starting with the most critical assets. Verify that the update successfully mitigates the injection vector before proceeding to less critical systems.

What to do and how to stay safe: YS-infoware

• Audit all BA-Workflow installations to confirm they are running version 3.6 or later.
• Review authentication logs for suspicious activity that may indicate an attacker has gained access.
• Ensure strict password policies and multi-factor authentication are enforced to reduce the risk of credential theft.
• Monitor database activity for unexpected queries or mass deletion events while awaiting updates.
