# Security Issue Runbook

This runbook provides step-by-step guidance on handling a security advisory. Typically, it begins with a draft security advisory when we initiate the process outlined in this runbook. The draft security advisory is created by a contributor or a maintainer.

For information on what types of issues are considered security vulnerabilities and require a security advisory for resolution, please refer to [identifying a security issue](./security_need_to_know.md#identifying-a-security-issue).

## Step 1: Initial Response to Security Advisory

- Receive Security Advisory: When a new security advisory is received, the Incident Manager, typically the maintainer who opened the advisory, becomes the first responder. If the advisory was opened by someone else, a maintainer should take on the role of Incident Manager. The Incident Manager can hand off this role to another maintainer if necessary.
- Acknowledge Receipt: The Incident Manager should promptly acknowledge receipt of the advisory and communicate that the investigation will begin immediately. Security issues are the highest priority.

## Step 2: Investigating the Vulnerability

- Identify the Vulnerability: Reproduce the issue to understand the vulnerability. Determine which versions and platforms are affected. Fill out the advisory details with this information.
- Accept the Report: Accept the security report and create a temporary private fork to collaborate on a fix. Invite necessary helpers and stakeholders to this fork, as their input can be valuable.

## Step 3: Communication and Collaboration

- Use Non-Public Channels: Communicate through non-public channels, preferably email, during the resolution process. Avoid filing issues or pull requests on third-party repositories if they are involved.
- Workaround for Third-Party Dependencies: If third-party dependencies are involved, consider a workaround to patch the issue quickly unless the third party can release a fix promptly.

## Step 4: Finalizing and Preparing for Release

- Finalize Details: Once a fix is developed and the vulnerability is fully understood, finalize the advisory details and prepare for public release. Ensure the security issues are resolved in the private fork.
- Request CVE: Use the Big Green Button on the advisory to request a CVE number from GitHub staff.
- Advanced Disclosure Email: Decide on a disclosure date, typically within a week, and send an email to sec-announce@bytecodealliance.org about the upcoming security release. Other ways are also available to communicate the disclosure date.

``` markdown

The Wamr project would like to announce a forthcoming security release.

The release will be made available on approximately YYYY-MM-DD. Additionally, an advisory will be made available on the same date at https://github.com/advisories.

The highest severity issue fixed in this release is classified as XXX based on the CVSS classification scheme.
```

## Step 5: Preparing and Testing Patch Releases

- Prepare PRs for Patch Releases: Create pull requests in the private fork for each version being patched. Ensure each PR is ready to apply cleanly and includes release notes for each release branch.
- Run Full Test Suite: Run the full test suite locally for the main branch. Attempt to run as much of the CI matrix locally as possible.

## Step 6: Public Release and Communication

- Open Version Bump PRs: Open version bump pull requests on the public repository without including patch notes or release notes for the fix.
- Manually Make PRs from Private Fork: Transfer the necessary pull requests from the private fork to the public repository.
- Merge and Trigger Releases: Merge the version bump PRs and trigger the release process.
- Publish GitHub Advisories: Delete the private forks and use the Big Green Button to publish the advisory.
- Send Security Release Email: Send a follow-up email to sec-announce@bytecodealliance.org describing the security release. Other communication channels can also be used to inform users about the security release.

[Updated YYYY-MM-DD] Security release available.

WAMR release version X.Y.Z is now available. The binary release can be found on GitHub at https://github.com/bytecodealliance/wasm-micro-runtime/releases/tag/WAMR-Y.Y.Z. This release addresses the following security issues rated XXX: https://the link of the advisory

We’ll be conducting a full review of our security practices to ensure ample notification is provided for future security releases.
```

By following these steps, you can effectively manage and resolve security issues for your open source project, ensuring timely communication and collaboration while maintaining the integrity and security of your software.
