SQL Injection in @hypequery/clickhouse (CVE-2026-54658)
Summary
SQL injection in @hypequery/clickhouse (CVE-2026-54658). Successful exploitation can lead to full system takeover. Exploitable via String. Mitigation: upgrade to 2.0.2 or later.
Original description
The description as published by the source.
Hypequery is a TypeScript semantic layer for ClickHouse. Prior to 2.5.1, escapeValue() in packages/clickhouse/src/core/utils.ts did not escape backslashes before single quotes during parameter substitution, allowing attacker controlled query parameters with a trailing backslash to escape the closing quote and inject arbitrary SQL. This issue is fixed in version 2.0.2. Version 2.0.2 fixes string parameters, while version 2.5.1 fixes all known vectors. Upgrading to 2.5.1 or later is the only complete fix. In versions 2.0.2 through 2.5.0, serializing non-scalar parameters with JSON.stringify() before passing them is a workaround for the object/array vector only.
