Name of the Vulnerable Software and Affected Versions Frourio versions prior to v0.26.0

Description Frourio is a full stack framework for TypeScript. Users who use Frourio version prior to v0.26.0 and integrate with class-validator through the validators/ folder are subject to an input validation issue. Validators do not work properly for request bodies and queries in specific situations, and some input is not validated at all.

Recommendations Update Frourio to v0.26.0 or later and install class-transformer and reflect-metadata. As a temporary workaround, consider validating objects from requests with class-transformer in controllers manually, or prevent using validators.
