Bref is vulnerable to Denial Of Service (DoS). The vulnerability is due to improper clean up of temporary files after processing a MultiPart requests when the Event-Driven Function runtime is utilized and the handler is a RequestHandlerInterface. This allows an attacker to fill the Lambda instance disk by performing multiple MultiPart requests, which results in Denial of Service (DoS).
