Description
A flaw was found in body-parser. When the parser is configured with an invalid limit option, such as an unparseable string or a non-numeric value, the request body size check is bypassed. This allows a remote attacker to send arbitrarily large payloads, consuming excessive memory and CPU resources. This can lead to a Denial of Service (DoS) condition, making the application unavailable to legitimate users.
