Technical Description
Litestar is an Asynchronous Server Gateway Interface (ASGI) framework. Prior to version 2.13.0, the multipart form parser shipped with litestar expects the entire request body as a single byte string and there is no default limit for the total size of the request body. This allows an attacker to upload arbitrary large files wrapped in a `multipart/form-data` request and cause excessive memory consumption on the server. The multipart form parser in affected versions is vulnerable to this type of attack by design. The public method signature as well as its implementation both expect the entire request body to be available as a single byte string. It is not possible to accept large file uploads in a safe way using this parser. This may be a regression, as a variation of this issue was already reported in CVE-2023-25578. Limiting the part number is not sufficient to prevent out-of-memory errors on the server. A patch is available in version 2.13.0.
Remediation
Check the references section for vendor advisories and patches from litestar. Update litestar to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
