EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5% (38th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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 attempts to enforce read-only database access with a blocklist containing only seven SQL keywords. An authenticated user with AI feature access can submit dangerous statements or database functions that are absent from the read-only keyword blocklist, causing them to execute without SQL injection or keyword-obfuscation techniques. Depending on the database engine, configuration, and database-user privileges, this can expose or write files, access internal network resources, change database privileges, execute commands, or alter data. This issue is fixed in version 5.2.2.
