Doc Text:	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.	Story Points:	---

Description OSIDB Bzimport 2026-04-24 19:02:47 UTC

Axios is a promise based HTTP client for the browser and Node.js. From 1.0.0 to before 1.15.1, the FormDataPart constructor in lib/helpers/formDataToStream.js interpolates value.type directly into the Content-Type header of each multipart part without sanitizing CRLF (\r\n) sequences. An attacker who controls the .type property of a Blob/File-like object (e.g., via a user-uploaded file in a Node.js proxy service) can inject arbitrary MIME part headers into the multipart form-data body. This bypasses Node.js v18+ built-in header protections because the injection targets the multipart body structure, not HTTP request headers. This vulnerability is fixed in 1.15.1.
