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.

Litestar is an Asynchronous Server Gateway Interface (ASGI) framework. In versions 2.10.0 and prior, Litestar's `docs-preview.yml` workflow is vulnerable to Environment Variable injection which may lead to secret exfiltration and repository manipulation. This issue grants a malicious actor the permission to write issues, read metadata, and write pull requests. In addition, the `DOCS_PREVIEW_DEPLOY_TOKEN` is exposed to the attacker. Commit 84d351e96aaa2a1338006d6e7221eded161f517b contains a fix for this issue.

Litestar and Starlite is an Asynchronous Server Gateway Interface (ASGI) framework. Prior to 2.8.3, 2.7.2, and 2.6.4, a Local File Inclusion (LFI) vulnerability has been discovered in the static file serving component of LiteStar. This vulnerability allows attackers to exploit path traversal flaws, enabling unauthorized access to sensitive files outside the designated directories. Such access can lead to the disclosure of sensitive information or potentially compromise the server. The vulnerability is located in the file path handling mechanism within the static content serving function, specifically at `litestar/static_files/base.py`. This vulnerability is fixed in versions 2.8.3, 2.7.2, and 2.6.4.
