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.
