CVE-2016-2216 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 7.01% chance of exploitation in the next 30 days.
