+# 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.
+
+## 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.
+
+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.

+# Shared heap Sample introduction
+
+This is a sample to show how to use the shared heap feature in WAMR. The shared heap feature allows multiple WASM instances to share the same memory space. This feature is useful when you want to run multiple WASM instances in the same process and share data between them. The sandbox nature of WASM is still maintained in the shared heap by WAMR. But the data management and correct data synchronization in shared heap is relied on the user's implementation.
+
+> Note: The shared heap feature is experimental feature, it should be used with caution. It's optional and only available when building WAMR with the CMake cache variable `WAMR_BUILD_SHARED_HEAP` set to 1.
+
+## Build and run the sample
+
+To build the shared heap used in multi thread sample and the shared heap chain sample with following commands:
+
+```bash
+cmake -S . -B build
+cmake --build build
+```
+
+For the shared heap sample, it demonstrates how to create a shared heap and use it shares data between two WASM instances, which would satisfy most of the use cases. Use the following commands to run the sample:
+
+```bash
+cd build
+./shared_heap_test
+```
+
+For the shared heap chain sample. It chains a pre-allocated heap and a normal shared heap to one chain(linked list) as a whole and attaches/detaches all together, and pass the WASM address directly between two WASM instances. Use the following commands to run the sample:
+
+```bash
+cd build
+./shared_heap_chain_test
+```
+
+## How to use shared heap
+
+The shared heap is an advanced feature in WAMR that gives the user flexibility to share data between multiple WASM instances(it will be the same address mapping for different WASM instance) or between WebAssembly and the host without incurring any copy overhead. The shared heap can be regarded as an extension of the WebAssembly linear memory. But it also heavily relies on the user's implementation to manage the shared data correctly. The following are some takeaway points to help the user use the shared heap correctly.
+
+### Create and manage shared heap
+
+You can create a shared heap by calling the `wasm_runtime_create_shared_heap(SharedHeapInitArgs *init_args)` API. And based on the `init_args`, you can create a shared heap in two ways:
+
+1. WAMR managed shared heap: when only `init_args.size` is given and `init_args.pre_allocated_addr` stays as NULL, WAMR will allocate a shared heap(not from the linear memory) with the given size. The shared heap will be managed by WAMR, the wasm app or host(WAMR users) can dynamically manage memory from it by calling `wasm_runtime_shared_heap_malloc()` and `wasm_runtime_shared_heap_free()` on demand. Only the memory allocated from the shared heap is valid and can be shared, not the unallocated part of shared heap memory. And it will be automatically freed when runtime is destroyed(when `wasm_runtime_destroy()` is called).
+
+2. Preallocated shared heap: the user can also use a pre-allocated memory(it can be allocated from the system heap, or is a static global buffer, the correctness of its accessibility and size needs to be ensured by the user) as a shared heap by giving `init_args.pre_allocated_addr` and `init_args.size`. This kind of shared heap serves as an area for data exchange, primarily between the host and WebAssembly. Any data within this area can be directly accessed by both sides (assuming the layout of the data structure is known). For instance, the host can store large structured variables in this space, allowing the WebAssembly application to operate on them without the need for copying. And the pre-allocated memory will relies on user to manage its life cycle.
+
+After creation, the shared heap can be attached to a WASM instance(an additional segment appended to the end of the linear memory) by calling `wasm_runtime_attach_shared_heap(wasm_module_inst_t module_inst, wasm_shared_heap_t shared_heap)`. And it can be detached by calling `wasm_runtime_detach_shared_heap(wasm_module_inst_t module_inst)`. So that the data sharing can only happen between the WASM instances that have the same shared heap attached, complete by user's choice.
+
+#### Shared heap chain
+
+Sometimes you may want to use multiple shared heaps to attach together as a chain(linked list) and to share data more flexibly. You can call `wasm_runtime_chain_shared_heaps(wasm_shared_heap_t head, wasm_shared_heap_t body)` to chain two shared heaps together. The shared heap list remains one continuous shared heap in wasm app's point of view. To create a shared heap chain, the shared heaps can't be currently attached to any WASM instance.
+
+> PS: At most one shared heap in shared heap list can be  WAMR managed shared heap, the rest have to be the pre-allocated shared heap.
