CVE-2025-43015Network attack vector

Remote service exposure via wildcard port binding

Published Apr 17, 2025 · Updated Apr 17, 2025

Insecure port binding in JetBrains RubyMine before 2025.1 allows remote attackers to reach remote-interpreter services on all interfaces. The remote Interpreter configuration overwrites selected port bindings with wildcard-address listeners, exposing services beyond the intended interface. A remote interpreter must be configured, and network access to the host then enables unauthenticated interaction with the exposed services.
