Description

Salvo is a Rust web framework. Prior to version 0.89.3, Salvo's form data parsing implementations (`form_data()` method and `Extractible` macro) do not enforce payload size limits before reading request bodies into memory. This allows attackers to cause Out-of-Memory (OOM) conditions by sending extremely large payloads, leading to service crashes and denial of service. Version 0.89.3 contains a patch.
