CVE-2026-27005Public exploitNetwork attack vector

Database reads and writes via unescaped date variables

Published Mar 6, 2026 · Updated Mar 6, 2026

SQL injection in Chartbrew before 4.8.3 allows remote attackers to read or alter connected MySQL or PostgreSQL databases. The applyMysqlOrPostgresVariables date branch in server/modules/applyVariables.js wraps runtime and default values in quotes without escaping embedded single quotes. Unauthenticated filter and query endpoints pass request variables into that branch; exploitation requires a chart with a date binding, and database privileges bound the readable, writable, or deletable data.
