{"cve":"CVE-2026-54658","nvd":{"published":"2026-07-28T23:17:08.913","modified":"2026-08-04T21:16:36.853","status":"Deferred","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-89"],"references":["https://github.com/hypequery/hypequery/blob/main/packages/clickhouse/CHANGELOG.md#202","https://github.com/hypequery/hypequery/commit/2879161a810fed2c2222f785816ff05510976960","https://github.com/hypequery/hypequery/commit/2dc1df7bae","https://github.com/hypequery/hypequery/commit/4dfa9d77d70a08b970e722268b75ca7d13db0bdf","https://github.com/hypequery/hypequery/pull/349"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:46:40.600842820+00:00"},"epss":{"cve":"CVE-2026-54658","score":0.00816,"percentile":0.57106,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-6wcc-39rp-hh9p","url":"https://osv.dev/vulnerability/GHSA-6wcc-39rp-hh9p","summary":"@hypequery/clickhouse has SQL Injection in parameter escaping that allows arbitrary SQL execution","modified":"2026-08-04T20:45:18.872507897Z","packages":[{"ecosystem":"npm","name":"@hypequery/clickhouse","purl":"pkg:npm/%40hypequery/clickhouse","ranges":["<2.5.1"],"fixed":["2.5.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
