### Summary An authenticated user with Creator role can inject arbitrary SQL via the DATEADD formula's unit parameter. ### Details The third argument (unit) of `DATEADD` was interpolated directly into `knex.raw()` queries after only stripping quote characters. Validation in `formulas.ts` only checked `Literal` AST node types — non-Literal types bypassed validation entirely. Affected MySQL, PostgreSQL, and SQLite function mappings. ### Impact SQL injection allowing data exfiltration or modification, scoped to the connected database. ### Credit This issue was reported by [@q1uf3ng](https://github.com/q1uf3ng).
