{"id":"CVE-2026-33442","summary":"Kysely has a MySQL SQL Injection via Backslash Escape Bypass in non-type-safe usage of JSON path keys.","details":"Kysely is a type-safe TypeScript SQL query builder. In versions 0.28.12 and 0.28.13, the `sanitizeStringLiteral` method in Kysely's query compiler escapes single quotes (`'` → `''`) but does not escape backslashes. On MySQL with the default `BACKSLASH_ESCAPES` SQL mode, an attacker can inject a backslash before a single quote to neutralize the escaping, breaking out of the JSON path string literal and injecting arbitrary SQL. Version 0.28.14 fixes the issue.","aliases":["GHSA-fr9j-6mvq-frcv"],"modified":"2026-07-08T08:00:10.643886376Z","published":"2026-03-26T17:01:57.866Z","database_specific":{"cwe_ids":["CWE-89"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33442.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33442.json"},{"type":"ADVISORY","url":"https://github.com/kysely-org/kysely/security/advisories/GHSA-fr9j-6mvq-frcv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33442"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kysely-org/kysely","events":[{"introduced":"afc81a1a11a139114b891abd654424fcd8b6afaa"},{"fixed":"91cf3733b2a419f5b17dff118cedb7052ab5300d"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:kysely:kysely:*:*:*:*:*:node.js:*:*","extracted_events":[{"introduced":"0.28.12"},{"fixed":"0.28.14"}]}}],"versions":["v0.28.13","v0.28.12"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33442.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
