-# Reporting security issues
+# Security Policy
 
-The project maintainers take security seriously. If you discover a security
-issue, please bring it to their attention right away!
+The maintainers of Docker Buildx take security seriously. If you discover
+a security issue, please bring it to their attention right away!
 
-**Please _DO NOT_ file a public issue**, instead send your report privately to
-[security@docker.com](mailto:security@docker.com).
+## Reporting a Vulnerability
 
-Security reports are greatly appreciated, and we will publicly thank you for it.
-We also like to send gifts—if you're into schwag, make sure to let
-us know. We currently do not offer a paid security bounty program, but are not
-ruling it out in the future.
+Please **DO NOT** file a public issue, instead send your report privately
+to [security@docker.com](mailto:security@docker.com).
+
+Reporter(s) can expect a response within 72 hours, acknowledging the issue was
+received.
+
+## Review Process
+
+After receiving the report, an initial triage and technical analysis is
+performed to confirm the report and determine its scope. We may request
+additional information in this stage of the process.
+
+Once a reviewer has confirmed the relevance of the report, a draft security
+advisory will be created on GitHub. The draft advisory will be used to discuss
+the issue with maintainers, the reporter(s), and where applicable, other
+affected parties under embargo.
+
+If the vulnerability is accepted, a timeline for developing a patch, public
+disclosure, and patch release will be determined. If there is an embargo period
+on public disclosure before the patch release, the reporter(s) are expected to
+participate in the discussion of the timeline and abide by agreed upon dates
+for public disclosure.
+
+## Accreditation
+
+Security reports are greatly appreciated and we will publicly thank you,
+although we will keep your name confidential if you request it. We also like to
+send gifts - if you're into swag, make sure to let us know. We do not currently
+offer a paid security bounty program at this time.
+
+## Supported Versions
+
+Once a new feature release is cut, support for the previous feature release is
+discontinued. An exception may be made for urgent security releases that occur
+shortly after a new feature release. Buildx does not offer LTS (Long-Term Support)
+releases. Refer to the [Support Policy](https://github.com/docker/buildx/blob/master/PROJECT.md#support-policy)
+for further details.

+## Project scope
+
+**Docker Buildx** is a Docker CLI plugin designed to extend build capabilities using BuildKit. It provides advanced features for building container images, supporting multiple builder instances, multi-node builds, and high-level build constructs. Buildx enhances the Docker build process, making it more efficient and flexible, and is compatible with both Docker and Kubernetes environments. Key features include:
+

+
+## Types of releases
+
+This project has feature releases, patch releases, and security releases.
+
+### Feature releases
+
+Feature releases are made from the development branch, followed by cutting a release branch for future patch releases, which may also occur during the code freeze period.
+
+#### Release Candidates
+
+Users can expect 2-3 release candidate (RC) test releases prior to a feature release. The first RC is typically released about one to two weeks before the final release.
+
+#### Support Policy
+
+Once a new feature release is cut, support for the previous feature release is discontinued. An exception may be made for urgent security releases that occur shortly after a new feature release. Buildx does not offer LTS (Long-Term Support) releases.
+
+#### Contributing to Releases
+
+Anyone can request that an issue or PR be included in the next feature or patch release milestone, provided it meets the necessary requirements.
+
+### Patch releases
+
+Patch releases should only include the most critical patches. Stability is vital, so everyone should always use the latest patch release.
+
+If a fix is needed but does not qualify for a patch release because of its code size or other criteria that make it too unpredictable, we will prioritize cutting a new feature release sooner rather than making an exception for backporting.
+
+Following PRs are included in patch releases
+
+- `priority/P0` fixes
+- `priority/P1` fixes, assuming maintainers don’t object because of the patch size
+- `priority/P2` fixes, only if (both required)
+    - proposed by maintainer
+    - the patch is trivial and self-contained
+- Documentation-only patches
+- Vendored dependency updates, only if:
+    - Fixing (qualifying) bug or security issue in Buildx
+    - The patch is small, else a forked version of the dependency with only the patches required
+
+New features do not qualify for patch release.
+
+## Milestones
+
+Milestones are used to help identify what releases a contribution will be in. 
+
+- The `v0.next` milestone collects unblocked items planned for the next 2-3 feature releases but not yet assigned to a specific version milestone.
+- The `v0.backlog` milestone gathers all triaged items considered for the long-term (beyond the next 3 feature releases) or currently unfit for a future release due to certain conditions. These items may be blocked and need to be unblocked before progressing.
+
+## Triage process
+
+Triage provides an important way to contribute to an open-source project. When submitted without an issue this process applies to Pull Requests as well. Triage helps ensure work items are resolved quickly by:
+
+- Ensuring the issue's intent and purpose are described precisely. This is necessary because it can be difficult for an issue to explain how an end user experiences a problem and what actions they took to arrive at the problem.
+- Giving a contributor the information they need before they commit to resolving an issue.
+- Lowering the issue count by preventing duplicate issues.
+- Streamlining the development process by preventing duplicate discussions.
+
+If you don't have time to code, consider helping with triage. The community will thank you for saving them time by spending some of yours. The same basic process should be applied upon receipt of a new issue.
+
+1. Verify essential information
+2. Classify the issue
+3. Prioritizing the issue
+
+### Verify essential information
+
+Before advancing the triage process, ensure the issue contains all necessary information to be properly understood and assessed. The required information may vary by issue type, but typically includes the system environment, version numbers, reproduction steps, expected outcomes, and actual results.
+
+- **Exercising Judgment**: Use your best judgment to assess the issue description’s completeness.
+- **Communicating Needs**: If the information provided is insufficient, kindly request additional details from the author. Explain that this information is crucial for clarity and resolution of the issue, and apply the `needs/more-information` label to indicate a response from the author is required.
+
+### Classify the issue
+
+An issue will typically have multiple labels. These are used to help communicate key information about context, requirements, and status. At a minimum, a properly classified issue should have:
+
+- (Required) One or more [`area/*`](#area) labels
+- (Required) One [`kind/*`](#kind) label  to indicate the type of issue
+- (Required if `kind/bug`) A [`priority/*`](#priority) label
+
+When assigning a decision the following labels should be present:
+
+- (Required) One [`status/*`](#status) label  to indicate lifecycle status
+
+Additional labels can provide more clarity:
+
+- Zero or more [`needs/*`](#needs) labels to indicate missing items
+- Zero or more [`impact/*`](#impact) labels
+- One [`exp/*`](#exp) label
+
+## Prioritization guidelines for `kind/bug`
+
+When an issue or pull request of `kind/bug` is correctly categorized and attached to a milestone, the labels indicate the urgency with which it should be completed. 
+
+**priority/P0**
+
+Fixing this item is the highest priority. A patch release will follow as soon as a patch is available and verified. This level is used exclusively for bugs.
+
+Examples:
+
+- Regression in a critical code path
+- Panic in a critical code path
+- Corruption in critical code path or rest of the system
+- Leaked zero-day critical security
+
+**priority/P1**
+
+Items with this label should be fixed with high priority and almost always included in a patch release. Unless waiting for another issue, patch releases should happen within a week. This level is not used for features or enhancements.
+
+Examples:
+
+- Any regression, panic
+- Measurable performance regression
+- A major bug in a new feature in the latest release
+- Incompatibility with upgraded external dependency
+
+**priority/P2**
+
+This is the default priority and is implied in the absence of a `priority/` label. Bugs with this priority should be included in the next feature release but may land in a patch release if they are ready and unlikely to impact other functionality adversely. Non-bug issues with this priority should also be included in the next feature release if they are available and ready.
+
+Examples:
+
+- Confirmed bugs
+- Bugs in non-default configurations
+- Most enhancements

+
+### Examples
+
+#### Submitting a bug
+
+To help illustrate the issue life cycle let’s walk through submitting an issue as a potential bug in CI that enters a feedback loop and is eventually accepted as P2 priority and placed on the backlog.
+
+```mermaid
+flowchart LR
+
+	new([New issue])

+```
+
+## Pull request review process
+
+A thorough and timely review process for pull requests (PRs) is crucial for maintaining the integrity and quality of the project while fostering a collaborative environment.
+
+- **Labeling**: Most labels should be inherited from a linked issue. If no issue is linked an extended review process may be required.
+- **Continuous Integration**: With few exceptions, it is crucial that all Continuous Integration (CI) workflows pass successfully.
+- **Draft Status**: Incomplete or long-running PRs should be placed in "Draft" status. They may revert to "Draft" status upon initial review if significant rework is required.
+
+```mermaid
+flowchart LR
+  triage([Triage])
+  draft[Draft PR]
+  review[PR Review]
+  closed{{Close PR}}
+  merge{{Merge PR}}
+
+  subgraph feedback1[Feedback Loop]
+    draft
+  end
+  subgraph feedback2[Feedback Loop]
+     review
+  end
+
+  triage --> draft
+  draft --> review
+  review --> closed
+  review --> draft
+  review --> merge
+```
+
+## Handling stalled issues and pull requests
+
+Unfortunately, some issues or pull requests can remain inactive for extended periods. To mitigate this, automation is employed to prompt both the author and maintainers, ensuring that all contributions receive appropriate attention.
+
+**For Authors:**
+
+- **Closure of Inactive Items**: If your issue or PR becomes irrelevant or is no longer needed, please close it to help keep the project clean.
+- **Prompt Responses**: If additional information is requested, please respond promptly to facilitate progress.
+
+**For Maintainers:**

+- **Timely Responses**: Endeavor to address issues and PRs within a reasonable timeframe to keep the community actively engaged.
+- **Engagement with Stale Issues**: If an issue becomes stale due to maintainer inaction, re-engage with the author to reassess and revitalize the discussion.
+
+**Stale and Rotten Policy:**
+
+- An issue or PR will be labeled as **`stale`** after 14 calendar days of inactivity. If it remains inactive for another 30 days, it will be labeled as **`rotten`** and closed.
+- Authors whose issues or PRs have been closed are welcome to re-open them or create new ones and link to the original.
+
+**Skipping Stale Processing:**
+
+- To prevent an issue or PR from being marked as stale, label it as **`frozen`**.
+
+**Exceptions to Stale Processing:**
+
+- Issues or PRs marked as **`frozen`**.
+- Issues or PRs assigned to a milestone.
+
+## Moving to a discussion
+
+Sometimes, an issue or pull request may not be the appropriate medium for what is essentially a discussion. In such cases, the issue or PR will either be converted to a discussion or a new discussion will be created. The original item will then be labeled appropriately (**`kind/discussion`** or **`kind/question`**) and closed.
+
+If you believe this conversion was made in error, please express your concerns in the new discussion thread. If necessary, a reversal to the original issue or PR format can be facilitated.
+
+## Workflow automation
+
+To help expedite common operations, avoid errors and reduce toil some workflow automation is used by the project. This can include:
+
+- Stale issue or pull request processing
+- Auto-labeling actions
+- Auto-response actions
+- Label carry over from issue to pull request
+
+### Exempting an issue/PR from stale bot processing
+
+The stale item handling is configured in the [repository](link-to-config-file). To exempt an issue or PR from stale processing you can:
+
+- Add the item to a milestone
+- Add the `frozen` label to the item
+
+## Updating dependencies
+
+- **Runtime Dependencies**: Use the latest stable release available when the first Release Candidate (RC) of a new feature release is cut. For patch releases, update to the latest corresponding patch release of the dependency.
+- **Other Dependencies**: Always permitted to update to the latest patch release in the development branch. Updates to a new feature release require justification, unless the dependency is outdated. Prefer tagged versions of dependencies unless a specific untagged commit is needed. Go modules should specify the lowest compatible version; there is no requirement to update all dependencies to their latest versions before cutting a new Buildx feature release.
+- **Patch Releases**: Vendored dependency updates are considered for patch releases, except in the rare cases specified previously.
+- **Security Considerations**: A security scanner report indicating a non-exploitable issue via Buildx does not justify backports.

+### `target.entitlements`
+
+Entitlements are permissions that the build process requires to run.
+
+Currently supported entitlements are:
+
+- `network.host`: Allows the build to use commands that access the host network. In Dockerfile, use [`RUN --network=host`](https://docs.docker.com/reference/dockerfile/#run---networkhost) to run a command with host network enabled.
+
+- `security.insecure`: Allows the build to run commands in privileged containers that are not limited by the default security sandbox. Such container may potentially access and modify system resources. In Dockerfile, use [`RUN --security=insecure`](https://docs.docker.com/reference/dockerfile/#run---security) to run a command in a privileged container.
+
+```hcl
+target "integration-tests" {
+  # this target requires privileged containers to run nested containers
+  entitlements = ["security.insecure"]
+}
+```
+
+Entitlements are enabled with a two-step process. First, a target must declare the entitlements it requires. Secondly, when invoking the `bake` command, the user must grant the entitlements by passing the `--allow` flag or confirming the entitlements when prompted in an interactive terminal. This is to ensure that the user is aware of the possibly insecure permissions they are granting to the build process.

+### `target.network`
+
+Specify the network mode for the whole build request. This will override the default network mode
+for all the `RUN` instructions in the Dockerfile. Accepted values are `default`, `host`, and `none`.
+
+Usually, a better approach to set the network mode for your build steps is to instead use `RUN --network=<value>`
+in your Dockerfile. This way, you can set the network mode for individual build steps and everyone building
+the Dockerfile gets consistent behavior without needing to pass additional flags to the build command.
+
+If you set network mode to `host` in your Bake file, you must also grant `network.host` entitlement when
+invoking the `bake` command. This is because `host` network mode requires elevated privileges and can be a security risk.
+You can pass `--allow=network.host` to the `docker buildx bake` command to grant the entitlement, or you can
+confirm the entitlement when prompted if you are using an interactive terminal.

-- `id` - ID of the secret. Defaults to `env` name.
-- `env` - Secret environment variable. `id` used if unset, otherwise will look for `src`, `source` if `id` unset.
+##### `type=env` usage
+
+In the following example, `type=env` is automatically detected because an
+environment variable matching `id` is set.
+
+```console
+$ SECRET_TOKEN=token docker buildx build --secret id=SECRET_TOKEN .
+```
 
 ```dockerfile
 # syntax=docker/dockerfile:1
 FROM node:alpine
 RUN --mount=type=bind,target=. \
-  --mount=type=secret,id=SECRET_TOKEN \
-  SECRET_TOKEN=$(cat /run/secrets/SECRET_TOKEN) yarn run test
+  --mount=type=secret,id=SECRET_TOKEN,env=SECRET_TOKEN \
+  yarn run test
 ```
 
+In the following example, the build argument `SECRET_TOKEN` is set to contain
+the value of the environment variable `API_KEY`.
+
 ```console
-$ SECRET_TOKEN=token docker buildx build --secret id=SECRET_TOKEN .
+$ API_KEY=token docker buildx build --secret id=SECRET_TOKEN,env=API_KEY .
 ```
 
+You can also specify the name of the environment variable with `src` or `source`:
+
+```console
+$ API_KEY=token docker buildx build --secret type=env,id=SECRET_TOKEN,src=API_KEY .
+```
+
+> [!NOTE]
+> Specifying the environment variable name with `src` or `source`, you are
+> required to set `type=env` explicitly, or else Buildx assumes that the secret
+> is `type=file`, and looks for a file with the name of `src` or `source` (in
+> this case, a file named `API_KEY` relative to the location where the `docker
+> buildx build` command was executed.
