Name of the Vulnerable Software and Affected Versions Dgraph versions prior to 25.4.0
Description Dgraph Zero registers administrative HTTP routes on port 6080 without authentication when the administrative interface is enabled. A remote unauthenticated attacker with access to the Zero HTTP port can disrupt the Zero control plane and destabilize Alpha nodes. This is achieved by interacting with the following endpoints:
  • '/state' to read topology
  • '/assign' to allocate identifiers
  • '/moveTablet' for administrative access
  • '/removeNode' to remove membership, which accepts id and group variables and passes them to the Server.RemoveNode() function, where group 0 can trigger ProposePeerRemoval().
Recommendations Update to version 25.4.0. As a temporary mitigation, restrict access to the Zero HTTP port 6080 or disable the administrative interface.
