Description Impact Improper header parsing. An attacker could sneak in a newline (\n) into both the header names and values. While the specification states that \r\n\r\n is used to terminate the header list, many servers in the wild will also accept \n\n. Patches The issue is patched in 1.9.1 and 2.4.5. Workarounds There are no known workarounds. References https://www.rfc-editor.org/rfc/rfc7230#section-3.2.4
