CVE-2026-32306Public exploitNetwork attack vector

Cross-tenant data compromise via aggregate SQL injection

Published Mar 12, 2026 · Updated Mar 12, 2026

SQL injection in OneUptime before 10.0.23 allows remote authenticated users to read and modify ClickHouse data via aggregate requests. StatementGenerator passes user-controlled aggregation types and column names to Statement.append(), which concatenates them into trusted SQL without validation or binding. Any registered user can reach the telemetry aggregate endpoints; exploitation crosses tenant boundaries and can alter data or execute commands through enabled ClickHouse table functions.
