CVE-2026-33468 is a high-severity SQL Injection vulnerability (CVSS 8.1) affecting Kysely versions prior to 0.28.14. The flaw, present in `DefaultQueryCompiler.sanitizeStringLiteral()`, allows attackers to inject arbitrary SQL by exploiting improper backslash escaping when Kysely is used with the MySQL dialect. This network-exploitable vulnerability, despite its high impact on confidentiality, integrity, and availability, has a high attack complexity. Currently, there is no evidence of active exploitation, no public exploit code, and community discussion is minimal, as indicated by its low EPSS score.
