CVE-2026-38924 PUBLISHED

Assigner: mitre
Reserved: 06.04.2026 Published: 14.09.2026 Updated: 14.09.2026

In Oraios AI Serena before 1.0.0, the listen address of the MCP server in HTTP mode is 0.0.0.0. NOTE: the Supplier observed that 0.0.0.0 was a "potential security hazard" but the Serena documentation, at the time of the issue report proposing 127.0.0.1 instead of 0.0.0.0, recommended "use a sandboxed environment for running Serena."
