CVE-2026-32306

OneUptime ClickHouse SQL Injection via Aggregate Query Parameters

State: Published
Severity: 10.0 Critical
Published: Mar 12, 2026
Updated: Mar 14, 2026
Reserved: Mar 11, 2026

Description

OneUptime is a solution for monitoring and managing online services. Prior to 10.0.23, the telemetry aggregation API accepts user-controlled aggregationType, aggregateColumnName, and aggregationTimestampColumnName parameters and interpolates them directly into ClickHouse SQL queries via the .append() method (documented as "trusted SQL"). There is no allowlist, no parameterized query binding, and no input validation. An authenticated user can inject arbitrary SQL into ClickHouse, enabling full database read (including telemetry data from all tenants), data modification, and potential remote code execution via ClickHouse table functions. This vulnerability is fixed in 10.0.23.
