Published

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.
