Description
A flaw was found in Axios, an HTTP client for Node.js. A remote attacker, by controlling the type property of a file-like object, could inject arbitrary MIME part headers into multipart form data. This vulnerability arises from insufficient sanitization of carriage return and line feed (CRLF) sequences in the Content-Type header. This could lead to information disclosure by allowing the attacker to manipulate the structure of the multipart body.
