CVE-2026-54349 Details
Description
Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to 5.2.1, SQL dashboard-variable substitution used attacker-controlled JavaScript replacement strings unsafely across SQL connectors and separately failed to escape backslashes for MySQL and MariaDB quoted contexts. The vulnerable surface is public and embedded dashboard/chart requests that call applyMysqlOrPostgresVariables. An unauthenticated user sends crafted URL filter values to a public or embedded chart backed by a stored SQL query. Replacement-string dollar sequences can alter SQL independently of the database engine, while MySQL and MariaDB backslash handling provides a second quoted-string escape path. The target must expose a public or embedded chart using URL-controlled variables in a SQL query; only the backslash branch is specific to MySQL and MariaDB. Injected SQL can read, modify, or delete data available to the configured database account. This issue is fixed in version 5.2.1.
A critical SQL injection vulnerability has been identified in Chartbrew, an open-source web application for creating charts from database and API data. This vulnerability exists in versions prior to 5.2.1, where SQL dashboard-variable substitution improperly handled user-controlled JavaScript replacement strings across SQL connectors. The issue allows an unauthenticated user to inject malicious SQL into queries executed by the application, potentially leading to unauthorized data access or manipulation. The vulnerability is present in public and embedded dashboard/chart requests that utilize URL-controlled variables in SQL queries, specifically affecting MySQL and MariaDB due to their unique backslash escape handling.
Users can upgrade to Chartbrew version 5.2.1 or later, where this vulnerability has been patched.
