0 CVE-2026-49756 is a CRLF injection vulnerability in the wojtekmach req library versions 0.5.3 before 0.6.0. It occurs because Req.Utils.encode_form_part/2 directly interpolates user-supplied name, filename, and content_type values into multipart headers without escaping or stripping CRLF characters. This allows an attacker to inject arbitrary headers or smuggle additional multipart fields by including CR or LF characters in these values, especially when using %File.Stream{} where filenames may contain such characters. The vulnerability enables multipart parameter smuggling in downstream requests. Join the discussion | CVE Database V5 | 06/08/2026, 15:20:24 UTC Added: 06/08/2026, 15:49:01 UTC |
