Apache Traffic Server accepts characters that are not allowed for HTTP field names and forwards malformed requests to origin servers.

This issue affects Apache Traffic Server: from 8.0.0 through 8.1.10, from 9.0.0 through 9.2.4. Users are recommended to upgrade to version 8.1.11 or 9.2.5, which fixes the issue.
