Upstream source description

Signal K Server before 2.33.0 contains a missing authentication vulnerability that allows unauthenticated remote attackers to download log archives via the /skServer/ziplogs endpoint. Attackers can extract the JWT secretKey from security.json in the ZIP, forge administrator tokens, and create persistent admin accounts for full server control.
