Litestar does not escape url paths when logging exceptions. This makes logger vulnerable to CRLF injection if logging level is configured to debug or log_exceptions is set to "always", which allows attackers to inject newlines and forge log entries.
Litestar offers multiple methods to return a parsed representation of the request body, as well as extractors that rely on those parsers to map request content to structured data types. Multiple of those parsers do not have size limits when reading the request body into memory, which allows an attacker to cause excessive memory consumption on the server by sending large requests.
Litestar's docs-preview.yml workflow is vulnerable to Environment Variable injection which may lead to secret exfiltration and repository manipulation.
Local File Inclusion via Path Traversal in LiteStar Static File Serving 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.
