Technical details
The Zero HTTP administrative surface registers routes including /removeNode, /assign, /state, and /moveTablet without authentication or authorization checks. An unauthenticated remote POST to /removeNode with crafted id and group parameters triggers ProposePeerRemoval, which disrupts cluster membership state. The admin HTTP server is enabled by default (disable-admin-http=false), making the vulnerability exploitable on any network-reachable deployment.
