A flaw was found in the foreman-mcp-server. 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.
