      "title": "CRLF injection in Tesla.Multipart disposition parameters allows multipart part header injection",
      "summary": "Improper Encoding or Escaping of Output vulnerability in elixir-tesla tesla allows multipart part header injection via unescaped Content-Disposition parameter values.\n\nTesla.Multipart.part_headers_for_disposition/1 interpolates each disposition parameter as #{k}=\"#{v}\" with no validation of CR (\\r), LF (\\n), or double-quote characters. The values come verbatim from the caller via Tesla.Multipart.add_field/4 (the name parameter), Tesla.Multipart.add_file/3, and Tesla.Multipart.add_file_content/4 (both the filename parameter and other disposition opts). A \" in the value closes the quoted parameter early; a \\r\\n ends the Content-Disposition header line and starts a new part header (such as a forged Content-Type), or, after a second \\r\\n, ends the entire part header block and prepends bytes to the part body. The default-filename path in add_file/3 derives the filename via Path.basename/1, which does not strip CR or LF, so any application forwarding a partially-attacker-controlled file path inherits the same issue.\n\nThis issue affects tesla: from 0.8.0 before 1.18.3.",
