Denial of service vulnerability when parsing multipart request body
Summary
The request body parsing in starlite allows a potentially unauthenticated
attacker to consume a large amount of CPU time and RAM.
Details
The multipart body parser processes an unlimited number of file parts. The multipart body parser processes an unlimited number of field parts.
Impact
This is a remote, potentially unauthenticated Denial of Service vulnerability.
This vulnerability affects applications with a request handler that accepts
a Body(media_type=RequestEncodingType.MULTI_PART).
The large amount of CPU time required for processing requests can block all available worker processes and significantly delay or slow down the processing of legitimate user requests. The large amount of RAM accumulated while processing requests can lead to Out-Of-Memory kills. Complete DoS is achievable by sending many concurrent multipart requests in a loop.

Starlite is an Asynchronous Server Gateway Interface (ASGI) framework. Prior to version 1.5.2, the request body parsing in `starlite` allows a potentially unauthenticated attacker to consume a large amount of CPU time and RAM. The multipart body parser processes an unlimited number of file parts and an unlimited number of field parts. This is a remote, potentially unauthenticated Denial of Service vulnerability. This vulnerability affects applications with a request handler that accepts a `Body(media_type=RequestEncodingType.MULTI_PART)`. The large amount of CPU time required for processing requests can block all available worker processes and significantly delay or slow down the processing of legitimate user requests. The large amount of RAM accumulated while processing requests can lead to Out-Of-Memory kills. Complete DoS is achievable by sending many concurrent multipart requests in a loop. Version 1.51.2 contains a patch for this issue.
