Summary
Frourio is a full stack framework, for TypeScript. Frourio users who uses frourio version prior to v0.26.0 and integration with class-validator through `validators/` folder are subject to a input validation vulnerability. Validators do not work properly for request bodies and queries in specific situations and some input is not validated at all. Users are advised to update frourio to v0.26.0 or later and to install `class-transformer` and `reflect-metadata`.
