Upgrade swift-server/async-http-client to version 1.4.1, 1.9.1, 1.12.1, 1.13.2 or higher.
Overview
swift-server/async-http-client is a HTTP Client library built on top of SwiftNIO
Affected versions of this package are vulnerable to CRLF Injection due to insufficient validation of HTTP header field values before sending them to the network. Users are vulnerable if they pass untrusted data into HTTP header field values without prior sanitization. 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.
