CVE-2026-4173 in Chat2DB
Summary
by MITRE • 03/16/2026
A flaw has been found in CodePhiliaX Chat2DB up to 0.3.7. This vulnerability affects the function exportTable/exportTableColumnComment/exportView/exportProcedure/exportTriggers/exportTrigger/updateProcedure of the file DMDBManage.java of the component Database Export Handler. This manipulation causes sql injection. It is possible to initiate the attack remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The vulnerability identified in CodePhiliaX Chat2DB version 0.3.7 represents a critical sql injection flaw within the database export handler component. This security weakness exists in the DMDBManage.java file and affects multiple export functions including exportTable, exportTableColumnComment, exportView, exportProcedure, exportTriggers, exportTrigger, and updateProcedure operations. The vulnerability stems from insufficient input validation and sanitization of user-supplied data within these database export routines, creating an avenue for malicious actors to inject arbitrary sql commands into the underlying database queries.
The technical exploitation of this vulnerability occurs through remote manipulation of the affected export functions, allowing attackers to execute unauthorized sql commands against the connected database system. This type of injection flaw typically arises when application code directly incorporates user input into sql query construction without proper parameterization or input filtering mechanisms. The vulnerability's classification aligns with CWE-89 which specifically addresses sql injection vulnerabilities in software applications. Attackers can leverage this weakness to perform unauthorized data access, modification, or deletion operations within the database, potentially leading to complete system compromise and data breaches.
The operational impact of this vulnerability extends beyond simple data theft, as it enables attackers to escalate privileges and gain deeper access to the underlying database infrastructure. The fact that exploitation has been published and is actively used in the wild significantly increases the risk profile for affected systems. Remote exploitation capabilities mean that attackers can target vulnerable installations from anywhere on the internet without requiring physical access or local network presence. This vulnerability particularly affects organizations using CodePhiliaX Chat2DB for database management tasks, as it essentially provides a backdoor into their data storage systems through legitimate export functionality.
Security practitioners should consider this vulnerability in the context of ATT&CK framework's T1071.004 technique which covers application layer protocol manipulation. The vulnerability also maps to T1566 attack pattern related to malicious file execution and command injection techniques. Organizations should immediately implement mitigations including input validation, parameterized queries, and access controls around the affected export functions. Additionally, network segmentation and monitoring of database connections can help detect unauthorized exploitation attempts. Given the vendor's lack of response to initial disclosure communications, organizations must take proactive measures to protect their systems using temporary workarounds or alternative database management approaches until a proper patch is available. The vulnerability highlights the critical importance of secure coding practices in database interaction components and demonstrates how seemingly legitimate functionality can become a security risk when input handling is inadequate.
