CVE-2026-33468
Description
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.
