**Name of the Vulnerable Software and Affected Versions** Fiber versions 2.52.6 through 2.52.6 **Description** The issue affects the `fiber.Ctx.BodyParser` functionality, which can map flat data to nested slices using `key[idx]value` syntax. However, 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. **Recommendations** For Fiber versions 2.52.6, update to version 2.52.7 to resolve the issue. As a temporary workaround, consider restricting the use of the `fiber.Ctx.BodyParser` functionality to minimize the risk of exploitation. Avoid using the `key[idx]value` syntax with negative `idx` values in the affected API endpoint until the issue is resolved.
