Fiber is an Express-inspired web framework written in Go. Starting in version 2.52.6 and prior to version 2.52.7, can map flat data to nested slices using syntax, but when idx is negative, it causes a panic instead of returning an error stating it cannot process the data. Since this data is user-provided, this could lead to denial of service for anyone relying on this functionality. Version 2.52.7 fixes the issue.
