Security Policy

VLMP is a network-facing media server that can hold your personal library and, via federation, connect to other people's servers. Security is taken seriously, even though this is a personal open-source project.

Supported versions

Only the latest released version receives security fixes. There are no long-term support branches.

Reporting a vulnerability

Please do not open a public GitHub issue for security problems.

Report privately via GitHub Security Advisories ("Report a vulnerability" on the Security tab). This keeps the details private until a fix is available.

When reporting, please include:

  • A description of the issue and its impact
  • Steps to reproduce (a proof of concept if you have one)
  • Affected version / commit
  • Any suggested remediation

What to expect

This is a best-effort, single-maintainer project. Realistic expectations:

  • Acknowledgement: within about a week
  • Assessment & fix: depends on severity and complexity; critical issues are prioritized
  • Disclosure: coordinated — a public advisory is published once a fix ships, with credit to the reporter unless you prefer to remain anonymous

Scope

In scope: the server (auth, streaming, federation, admin surfaces), the client, and the Windows installer.

Out of scope: vulnerabilities in third-party dependencies (report those upstream), issues that require physical access to an already-compromised host, and misconfiguration of the deployment environment (e.g. exposing the raw port to the internet without TLS — see the README's remote-access guidance).

Hardening background

VLMP has been through several adversarial audit passes covering performance, code, logic, resilience, usability, and access control. Historical findings and the deferred queue are documented under docs/ (e.g. docs/AUDIT-2026-07-19.md). Reviewing those is a good starting point before reporting, to avoid duplicating already-tracked items.

Deploying safely

  • Always set a strong VLMP_JWT_SECRET (or VLMP_JWT_SECRET_FILE). Never ship the default.
  • Do not port-forward VLMP directly to the internet. Put it behind a mesh VPN (Tailscale/WireGuard) or a TLS-terminating reverse proxy / tunnel.
  • Keep FFmpeg and Node.js up to date.
  • Restrict the data directory and any config files to the service account.
