Security reports are welcome and should be handled privately before public disclosure.

UModel Open Source is maintained on the main development line until stable release branches are published. Security fixes are accepted there first and should be backported once versioned release branches exist.

Do not open a public issue for a vulnerability.

Preferred reporting paths:

1. Use GitHub private vulnerability reporting if it is enabled for the repository.
2. If private vulnerability reporting is not available, contact the maintainers through the private channel listed by the hosting organization.

Please include:

• Affected commit, branch, or release.
• Reproduction steps.
• Expected and observed behavior.
• Impact assessment.
• Any known workaround.

Maintainers should acknowledge a complete report within 5 business days, triage severity, and coordinate a fix or disclosure plan with the reporter.

Current open-source security defaults:

• make dev, Docker, and Compose use file.memory local persistence.
• MCP write tools are disabled by default.
• AgentGateway resources expose metadata and templates, not runtime rows.
• This release does not include multi-tenant authorization or cloud-hosted control plane behavior.

Do not use the local development server as an internet-facing production service without adding authentication, authorization, transport security, rate limits, audit logging, and deployment hardening.
