{"id":"CVE-2026-32763","aliases":["GHSA-wmrf-hv6w-mr66"],"url":"https://o3.security/vulnerability/CVE-2026-32763","summary":"SQL Injection via unsanitized JSON path keys when ignoring/silencing compilation errors or using `Kysely<any>`.","details":"Kysely is a type-safe TypeScript SQL query builder. Versions up to and including 0.28.11 has a SQL injection vulnerability in JSON path compilation for MySQL and SQLite dialects. The `visitJSONPathLeg()` function appends user-controlled values from `.key()` and `.at()` directly into single-quoted JSON path string literals (`'$.key'`) without escaping single quotes. An attacker can break out of the JSON path string context and inject arbitrary SQL. This is inconsistent with `sanitizeIdentifier()`, which properly doubles delimiter characters for identifiers — both are non-parameterizable SQL constructs requiring manual escaping, but only identifiers are protected. Version 0.28.12 fixes the issue.","published":"2026-03-19T23:14:58.747Z","modified":"2026-08-07T11:48:54.695171580Z","cvss":{"score":8.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"kysely","fixedVersion":"0.28.12"}],"fix":{"url":"https://github.com/kysely-org/kysely/commit/0a602bff2f442f6c26d5e047ca8f8715179f6d24","label":"kysely-org/kysely@0a602bf"},"references":[{"type":"WEB","url":"https://github.com/kysely-org/kysely/releases/tag/v0.28.12"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32763.json"},{"type":"ADVISORY","url":"https://github.com/kysely-org/kysely/security/advisories/GHSA-wmrf-hv6w-mr66"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32763"},{"type":"FIX","url":"https://github.com/kysely-org/kysely/commit/0a602bff2f442f6c26d5e047ca8f8715179f6d24"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:48:54.695171580Z"}}
