Detailsinfo

A vulnerability was found in Chartbrew up to 5.2.1. It has been classified as critical. This affects the function runQuery of the file server/modules/ai/orchestrator/tools/runQuery.js of the component SQL Query Execution. The manipulation of the argument row_limit with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to 5.2.2, Chartbrew's runQuery() implementation in server/modules/ai/orchestrator/tools/runQuery.js interpolates the AI tool's row_limit parameter into a SQL LIMIT clause without runtime integer validation. The read-only keyword check runs before this value is appended, so an authenticated user who can influence a model-generated non-integer row_limit can add SQL that bypasses the earlier check. Successful exploitation can execute arbitrary statements against the connected database, including reading or changing data and, where database permissions permit, accessing files or executing operating-system commands. This issue is fixed in version 5.2.2.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-61852 since 07/10/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1505 for this issue.
