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.
AnalysisAI
Axios HTTP client versions 1.0.0 through 1.15.0 allow header injection in multipart form-data bodies through unsanitized CRLF sequences in the Content-Type header of individual parts. An attacker controlling a Blob/File object's .type property (such as via user-uploaded files in a Node.js proxy service) can inject arbitrary MIME headers into the multipart body, bypassing Node.js v18+ built-in header protections. …
