Is this vulnerability remotely exploitable?

It can be, if an external user can influence the string values used in Kysely's affected builders and those values are ultimately executed against a MySQL database with backslash escapes enabled. The exploitability depends on how the application exposes these code paths.

What level of access does an attacker need to exploit this?

The attacker needs the ability to supply or manipulate data that is passed into APIs that use `ImmediateValueTransformer` for MySQL query compilation. This could range from crafted HTTP requests in a web app to tampering with configuration or metadata that the application uses to construct schema-related SQL.

What is the safest general fix pattern?

The most robust fix is to avoid inlining user-controlled values in SQL and rely on parameterized queries. Where literals are unavoidable, use a thoroughly tested, dialect-aware escaping mechanism that neutralizes all special characters relevant to the database, and confine schema-building constructs to static, developer-controlled inputs.
