CVE-2026-42072Network attack vector

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.
