Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

Versions of Async HTTP Client prior to 1.13.2 is vulnerable to a form of targeted request manipulation called CRLF injection. This vulnerability was the result of insufficient validation of HTTP header field values before sending them to the network. Users is vulnerable if they pass untrusted data into HTTP header field values without prior sanitisation. Common use-cases here might be to place usernames from a database into HTTP header fields. This vulnerability allows attackers to inject new HTTP header fields, or entirely new requests, into the data stream. This can cause requests to be understood very differently by the remote server than was intended. In general, this is unlikely to result in data disclosure, but it can result in a number of logical errors and other misbehaviours.

All versions before 1.4.1, all versions starting from 1.5.0 before 1.9.1, all versions starting from 1.10.0 before 1.12.1, all versions starting from 1.13.0 before 1.13.2

Upgrade to versions 1.4.1, 1.9.1, 1.12.1, 1.13.2 or above.
