Kysely is a type-safe TypeScript SQL query builder. Prior to version 0.28.14, Kysely's only escapes single quotes by doubling them ( → ) but does not escape backslashes. When used with the MySQL dialect (where 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 to inline values — specifically and . Version 0.28.14 contains a fix.
