Detailsinfo

A vulnerability, which was classified as problematic, was found in gofiber fiber 2.52.6. Affected is the function fiber.Ctx.BodyParser. The manipulation with an unknown input leads to a array index vulnerability. CWE is classifying the issue as CWE-129. The product uses untrusted input when calculating or using an array index, but the product does not validate or incorrectly validates the index to ensure the index references a valid position within the array. This is going to have an impact on availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability is traded as CVE-2025-48075 since 05/15/2025. The exploitability is told to be easy. It is possible to launch the attack remotely.
