Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Graylog2-server versions 6.1.0 through 6.1.8 are affected. HTTP inputs configured to authenticate with a required header and value still ingest messages when that header is missing or has the wrong value, even though the client receives a 401 response. The source does not describe the attacker's position or access requirements. Upgrade to Graylog2-server 6.1.9. If upgrading is not possible, disable HTTP-based inputs and use only authenticated pull-based inputs.
