Unauthorized graph-data access via wildcard Bolt binding
Published May 8, 2026 · Updated May 8, 2026
Improper network binding in NornicDB before 1.0.42-hotfix allows remote attackers on the local network to read and alter graph data. The Bolt server's ListenAndServe path builds the listener address from only the port, so net.Listen receives an empty host and binds every interface despite the configured host. Exposure requires LAN reachability and unchanged default admin:password credentials; successful access permits arbitrary Cypher reads, writes, and deletion.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
