+# Security Policy
+
+## Reporting a Vulnerability
+
+Thank you for helping keep NodeWarden safe.
+
+Please **do not report security vulnerabilities through public GitHub issues, discussions, pull requests, or chat groups**.
+
+Use GitHub Private Vulnerability Reporting instead:
+
+1. Open the NodeWarden repository on GitHub.
+2. Go to **Security and quality**.
+3. Click **Report a vulnerability**.
+4. Submit the report privately.
+
+NodeWarden is independent from Bitwarden. Please do not report NodeWarden-specific issues to the official Bitwarden team.
+
+## What to Include
+
+Please include as much detail as possible:
+
+* A clear description of the vulnerability.
+* Steps to reproduce.
+* Affected version, commit, or deployment method.
+* Affected area, such as login, sync, vault data, attachments, Send, import/export, backup/restore, Passkey, WebAuthn, or API routes.
+* Expected behavior and actual behavior.
+* Security impact, such as authentication bypass, authorization bypass, replay, cross-user access, token misuse, data leakage, or secret exposure.
+* Proof of concept, logs, screenshots, or request examples, if safe to share privately.
+
+Please redact real passwords, tokens, private keys, recovery keys, vault data, and other secrets before submitting.
+
+## Scope
+
+Security reports are welcome for issues affecting NodeWarden itself, including:
+
+* Authentication and session handling.
+* User authorization and cross-user access.
+* Vault data, cipher sync, attachments, and Send.
+* Import, export, backup, and restore.
+* Passkey, WebAuthn, and two-factor authentication.
+* Secret handling and provider credentials.
+* Cloudflare Workers, D1, R2, KV, WebDAV, or S3 behavior caused by NodeWarden code or documentation.
+
+## Out of Scope
+
+The following are usually out of scope:
+
+* Issues only affecting third-party services or user infrastructure.
+* Misconfigured personal deployments not caused by NodeWarden defaults.
+* Social engineering or phishing.
+* Denial-of-service testing.
+* Scanner-only reports without a practical exploit path.
+* Reports that only mention outdated dependencies without showing real impact.
+
+## Response
+
+NodeWarden is maintained on a best-effort basis.
+
+We aim to acknowledge valid private reports within 72 hours, investigate the issue, and release a fix or mitigation when appropriate.
+
+Please do not publicly disclose vulnerability details before a fix or mitigation is available.
+
+## Supported Versions
+
+Security fixes are generally provided for the latest release and the latest code on the default branch.
+
+| Version        | Supported              |
+| -------------- | ---------------------- |
+| Latest release | Yes                    |
+| `main` branch  | Yes                    |
+| Older releases | Best effort            |
+| Modified forks | Not directly supported |
+
+## Rewards
+
+NodeWarden does not currently operate a paid bug bounty program.
