In Mitre's CVE dictionary: CVE-2019-19330.
More information:

Tim Düsterhus discovered that haproxy, a TCP/HTTP reverse proxy, did not properly sanitize HTTP headers when converting from HTTP/2 to HTTP/1. This would allow a remote user to perform CRLF injections.

For the stable distribution (buster), this problem has been fixed in version 1.8.19-1+deb10u1.

We recommend that you upgrade your haproxy packages.
