CVE-2026-54658 PUBLISHED

Hypequery is a TypeScript semantic layer for ClickHouse. Prior to 2.0.2, 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.
