{"id":"CVE-2026-33468","summary":"Kysely has a MySQL SQL Injection via Insufficient Backslash Escaping in `sql.lit(string)` usage or similar methods that append string literal values into the compiled SQL strings","details":"Kysely is a type-safe TypeScript SQL query builder. Prior to version 0.28.14, Kysely's `DefaultQueryCompiler.sanitizeStringLiteral()` only escapes single quotes by doubling them (`'` → `''`) but does not escape backslashes. When used with the MySQL dialect (where `NO_BACKSLASH_ESCAPES` is OFF by default), an attacker can use a backslash to escape the trailing quote of a string literal, breaking out of the string context and injecting arbitrary SQL. This affects any code path that uses `ImmediateValueTransformer` to inline values — specifically `CreateIndexBuilder.where()` and `CreateViewBuilder.as()`. Version 0.28.14 contains a fix.","aliases":["GHSA-8cpq-38p9-67gx"],"modified":"2026-04-10T05:43:05.523849Z","published":"2026-03-26T17:03:05.972Z","related":["CGA-7mcx-xcjh-v997"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-89"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33468.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33468.json"},{"type":"ADVISORY","url":"https://github.com/kysely-org/kysely/security/advisories/GHSA-8cpq-38p9-67gx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33468"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kysely-org/kysely","events":[{"introduced":"0"},{"fixed":"91cf3733b2a419f5b17dff118cedb7052ab5300d"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"0.28.14"}]}}],"versions":["0.10.0","0.10.1","0.11.0","0.11.1","0.11.2","0.11.3","0.11.4","0.12.0","0.12.1","0.12.2","0.13.0","0.14.0","0.14.1","0.15.0","0.15.1","0.15.2","0.15.3","0.16.0","0.16.1","0.16.10","0.16.11","0.16.2","0.16.3","0.16.4","0.16.5","0.16.6","0.16.7","0.16.8","0.16.9","0.17.0","0.17.2","0.17.3","0.18.0","0.18.1","0.19.0","0.19.1","0.19.10","0.19.11","0.19.12","0.19.2","0.19.3","0.19.4","0.19.5","0.19.6","0.19.7","0.19.8","0.19.9","0.20.0","0.20.1","0.21.0","0.21.1","0.21.2","0.21.3","0.21.4","0.21.5","0.21.6","0.22.0","0.23.0","0.23.1","0.23.2","0.23.3","0.23.4","0.23.5","0.24.0","0.24.2","0.25.0","0.26.0","0.26.1","0.26.2","0.26.3","0.27.0","0.27.1","0.27.2","0.27.3","0.27.4","0.27.5","0.27.6","0.28.0","0.28.1","0.28.2","0.7.8","0.7.9","0.9.0","0.9.1","0.9.2","0.9.3","0.9.4","0.9.5","0.9.6","0.9.7","0.9.8","0.9.9","v0.28.10","v0.28.11","v0.28.12","v0.28.13","v0.28.3","v0.28.4","v0.28.5","v0.28.6","v0.28.7","v0.28.8","v0.28.9"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33468.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"}]}
