Description

The vulnerability allows a remote non-authenticated attacker to manipulate data.

The HTTP header parsing code in Node.js 0.10.x before 0.10.42, 0.11.6 through 0.11.16, 0.12.x before 0.12.10, 4.x before 4.3.0, and 5.x before 5.6.0 allows remote attackers to bypass an HTTP response-splitting protection mechanism via UTF-8 encoded Unicode characters in the HTTP header, as demonstrated by %c4%8d%c4%8a.
