CVE-2025-48075
May 22, 2025
Fiber is an Express-inspired web framework written in Go. Starting in version 2.52.6 and prior to version 2.52.7, "fiber.Ctx.BodyParser" can map flat data to nested slices using "key[idx]value" 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 "fiber.Ctx.BodyParser" functionality. Version 2.52.7 fixes the issue.
