CVE-2026-27005 in Chartbrew
Summary
by MITRE • 03/06/2026
Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to version 4.8.3, an unauthenticated attacker can inject arbitrary SQL into queries executed against databases connected to Chartbrew (MySQL, PostgreSQL). This allows reading, modifying, or deleting data in those databases depending on the database user's privileges. This issue has been patched in version 4.8.3.

The vulnerability identified as CVE-2026-27005 affects Chartbrew, an open-source web application designed for database and API connectivity to generate visual charts. This application serves as a bridge between data sources and visualization interfaces, making it a critical component in data-driven environments. The flaw represents a significant security weakness that directly impacts the integrity and confidentiality of connected database systems, particularly those utilizing MySQL and PostgreSQL databases. The vulnerability exists within the application's query processing mechanisms, where insufficient input validation allows malicious actors to inject SQL commands without authentication.
The technical implementation of this vulnerability stems from inadequate sanitization of user inputs within the application's database query execution pathways. Attackers can exploit this weakness by crafting malicious SQL injection payloads that bypass authentication mechanisms and are subsequently executed against connected database systems. This flaw specifically targets the application's handling of database queries, allowing unauthenticated remote attackers to manipulate database operations through the Chartbrew interface. The vulnerability's impact is directly proportional to the privileges assigned to the database user account that Chartbrew utilizes for connecting to these systems, potentially enabling full data compromise including read, write, and delete operations.
From an operational standpoint, this vulnerability creates substantial risk for organizations relying on Chartbrew for data visualization and reporting. The unauthenticated nature of the attack means that any external party can potentially access database systems without requiring legitimate credentials, making it particularly dangerous in publicly accessible environments. The affected databases, including both MySQL and PostgreSQL implementations, face potential exposure to data exfiltration, data corruption, or unauthorized modifications that could compromise business intelligence and operational data. Organizations using Chartbrew in production environments without proper network segmentation or access controls face heightened risk of data breaches and compliance violations.
The remediation for CVE-2026-27005 involves upgrading to Chartbrew version 4.8.3, which includes proper input validation and sanitization mechanisms for database queries. This update addresses the root cause by implementing proper parameterized query execution and input filtering techniques that prevent malicious SQL payloads from being executed. Organizations should also implement network-level controls including firewall rules, access control lists, and segmentation to limit exposure of Chartbrew installations. The vulnerability aligns with CWE-89, which describes SQL injection flaws, and represents a common attack pattern documented in the MITRE ATT&CK framework under technique T1071.004 for application layer protocol manipulation, highlighting the need for robust input validation and secure coding practices in web applications that interact with database systems.
