A session management vulnerability in the MCP Server allows unauthenticated attackers to hijack active administrative sessions due to an improper cache of authenticated client connections, by trusting a non-secret session ID without re-validating authentication tokens and by logging all newly created session IDs to standard logs. This issue can result in privilege escalation and infrastructure-wide code execution."},{"lang":"es","value":"Se encontró una falla en el foreman-mcp-server. Una vulnerabilidad de gestión de sesiones en el Servidor MCP permite a atacantes no autenticados secuestrar sesiones administrativas activas debido a un caché inadecuado de conexiones de clientes autenticados, al confiar en un ID de sesión no secreto sin revalidar los tokens de autenticación y al registrar todos los ID de sesión recién creados en los registros estándar.
