drupal_warmup

Projects that follow the best practices below can voluntarily self-certify and show that they've achieved an Open Source Security Foundation (OpenSSF) best practices badge.

There is no set of practices that can guarantee that software will never have defects or vulnerabilities; even formal methods can fail if the specifications or assumptions are wrong. Nor is there any set of practices that can guarantee that a project will sustain a healthy and well-functioning development community. However, following best practices can help improve the results of projects. For example, some practices enable multi-person review before release, which can both help find otherwise hard-to-find technical vulnerabilities and help build trust and a desire for repeated interaction among developers from different companies. To earn a badge, all MUST and MUST NOT criteria must be met, all SHOULD criteria must be met OR be unmet with justification, and all SUGGESTED criteria must be met OR unmet (we want them considered at least). If you want to enter justification text as a generic comment, instead of being a rationale that the situation is acceptable, start the text block with '//' followed by a space. Feedback is welcome via the GitHub site as issues or pull requests There is also a mailing list for general discussion.

We gladly provide the information in several locales, however, if there is any conflict or inconsistency between the translations, the English version is the authoritative version.
If this is your project, please show your baseline badge status on your project page! The baseline badge status looks like this: Baseline badge level for project 14634 is baseline-1 Here is how to embed the baseline badge:
You can show your baseline badge status by embedding this in your markdown file:

    Please use SPDX license expression format; examples include "Apache-2.0", "BSD-2-Clause", "BSD-3-Clause", "GPL-2.0+", "LGPL-3.0+", "MIT", and "(BSD-2-Clause OR Ruby)". Do not include single quotes or double quotes.
    If there is more than one language, list them as comma-separated values (spaces optional) and sort them from most to least used. If there is a long list, please list at least the first three most common ones. If there is no language (e.g., this is a documentation-only or test-only project), use the single character "-". Please use a conventional capitalization for each language, e.g., "JavaScript".
    The Common Platform Enumeration (CPE) is a structured naming scheme for information technology systems, software, and packages. It is used in a number of systems and databases when reporting vulnerabilities.

    drupal_warmup is a small single-binary Go CLI enabling Drupal sites to reach high performance right after deployments.
    The tool is generic to any site that publishes an XML sitemap; the Drupal-specific parts are limited to an optional login and the cache-header column of its report.

    Enough for a badge!

    When a CI/CD task is executed with no permissions specified, the CI/CD system MUST default the task's permissions to the lowest permissions granted in the pipeline. [OSPS-AC-04.01]
    Configure the project's settings to assign the lowest available permissions to new pipelines by default, granting additional permissions only when necessary for specific tasks.

    The repository default workflow permission is read-only (default_workflow_permissions: read), so a job or workflow specifying nothing receives the lowest token. Every workflow additionally sets an explicit minimal top-level permissions block that jobs inherit, and elevated scopes are granted only on the individual jobs that require them.


    Enough for a badge!

    When an official release is created, that release MUST be assigned a unique version identifier. [OSPS-BR-02.01]
    Assign a unique version identifier to each release produced by the project, following a consistent naming convention or numbering scheme. Examples include SemVer, CalVer, or git commit id.

    Enough for a badge!

    When an official release is created, that release MUST contain a descriptive log of functional and security modifications. [OSPS-BR-04.01]
    Ensure that all releases include a descriptive change log. It is recommended to ensure that the change log is human-readable and includes details beyond commit messages, such as descriptions of the security impact or relevance to different use cases. To ensure machine readability, place the content under a markdown header such as "## Changelog".

    Official releases are produced by GoReleaser, triggered only on SemVer git tags (refs/tags/v*), and the release version is taken from the tag. Tag names are unique in Git, so each release has a unique version identifier. No release has been tagged yet; the process enforces uniqueness once one is.


    Enough for a badge!

    When a build and release pipeline ingests dependencies, it MUST use standardized tooling where available. [OSPS-BR-05.01]
    Use a common tooling for your ecosystem, such as package managers or dependency management tools to ingest dependencies at build time. This may include using a dependency file, lock file, or manifest to specify the required dependencies, which are then pulled in by the build system.

    The project uses Go modules (go.mod/go.sum) for all dependency ingestion, the standard tooling for the language, with checksum verification via go.sum and an explicit go mod verify step in the release pipeline. Dependabot manages updates through the same module files.


    Enough for a badge!

    When an official release is created, that release MUST be signed or accounted for in a signed manifest including each asset's cryptographic hashes. [OSPS-BR-06.01]
    Sign all released software assets at build time with a cryptographic signature or attestations, such as GPG or PGP signature, Sigstore signatures, SLSA provenance, or SLSA VSAs. Include the cryptographic hashes of each asset in a signed manifest or metadata file.

    GoReleaser emits checksums.txt with each asset's SHA-256 hash, and the release workflow signs it with a Sigstore keyless attestation (actions/attest, subject-checksums: checksums.txt) bound to the workflow's OIDC identity. The attestation is verifiable with gh attestation verify and published as a release asset, so every release asset is covered by a signed manifest of hashes.


    Enough for a badge!

    When the project has made a release, the project documentation MUST include a description of how the project selects, obtains, and tracks its dependencies. [OSPS-DO-06.01]
    It is recommended to publish this information alongside the project's technical & design documentation on a publicly viewable resource such as the source code repository, project website, or other channel.

    The README's "Dependencies" section describes how the project selects dependencies (stdlib and golang.org/x without review, others vetted), obtains them (Go modules with go.sum checksum verification and go mod verify in the release pipeline), and tracks them (go.mod/go.sum committed, Dependabot for scheduled updates).


    Enough for a badge!

    The project documentation MUST include instructions on how to build the software, including required libraries, frameworks, SDKs, and dependencies. [OSPS-DO-07.01]
    It is recommended to publish this information alongside the project's contributor documentation, such as in CONTRIBUTING.md or other developer task documentation. This may also be documented using Makefile targets or other automation scripts.

    The README's "Build from source" section states the sole prerequisite (Go 1.27.1+, per go.mod), notes that dependencies are fetched automatically by Go modules, and gives the clone-and-make build steps, with the other make targets and the release-only GoReleaser dependency described.


    Enough for a badge!

    The project documentation MUST include a list of project members with access to sensitive resources. [OSPS-GV-01.01]
    Document project participants and their roles through such artifacts as members.md, governance.md, maintainers.md, or similar file within the source code repository of the project. This may be as simple as including names or account handles in a list of maintainers, or more complex depending on the project's governance.

    The README's "Maintainers" section lists the project's sole member with access to sensitive resources (repository admin, CI/CD, and release signing) by name and GitHub handle.


    Enough for a badge!

    The project documentation MUST include descriptions of the roles and responsibilities for members of the project [OSPS-GV-01.02]
    Document project participants and their roles through such artifacts as members.md, governance.md, maintainers.md, or similar file within the source code repository of the project.

    The README's "Maintainers" section defines the project's one role, maintainer, and its responsibilities: reviewing and merging changes via pull request, releasing and signing, triaging issues and security reports, and dependency upkeep.


    Enough for a badge!

    The project documentation MUST include a guide for code contributors that includes requirements for acceptable contributions. [OSPS-GV-03.02]
    Extend the CONTRIBUTING.md or CONTRIBUTING/ contents in the project documentation to outline the requirements for acceptable contributions, including coding standards, testing requirements, and submission guidelines for code contributors. It is recommended that this guide is the source of truth for both contributors and approvers.

    CONTRIBUTING.md documents the contribution process (pull requests against the protected main branch) and the requirements for acceptable contributions: passing make (staticcheck, race-detector tests, build), tests for new behaviour, 100% coverage, gofmt-clean code, Conventional Commits, and GPL-3.0 licensing.


    Not enough for a badge.

    The version control system MUST require all code contributors to assert that they are legally authorized to make the associated contributions on every commit. [OSPS-LE-01.01]
    Include a DCO in the project's repository, requiring code contributors to assert that they are legally authorized to commit the associated contributions on every commit. Use a status check to ensure the assertion is made. A CLA also satisfies this requirement. Some version control systems, such as GitHub, may include this in the platform terms of service.

    drupal_warmup is a single-maintainer project. Every commit to date is authored by the sole maintainer, who is also the copyright holder, so there is no third-party contribution whose legal authorization a per-commit Developer Certificate of Origin sign-off would attest (https://developercertificate.org/). That mechanism exists to bind external contributors to the assertion; with no external code contributors, requiring a Signed-off-by line on every commit adds process without adding assurance. Contribution licensing is still documented: CONTRIBUTING.md states that opening a pull request offers the work under the project's GPL-3.0 license (https://github.com/fgm/drupal_warmup/blob/main/CONTRIBUTING.md). If external contributors join, the project will enforce the DCO through the DCO GitHub App (https://github.com/apps/dco) at that point.


    Enough for a badge!

    When a commit is made to the primary branch, any automated status checks for commits MUST pass or be manually bypassed. [OSPS-QA-03.01]
    Configure the project's version control system to require that all automated status checks pass or require manual acknowledgement before a commit can be merged into the primary branch. It is recommended that any optional status checks are NOT configured as a pass or fail requirement that approvers may be tempted to bypass.

    The default-branch ruleset requires the CI test job, CodeQL, and dependency-review checks to pass before a pull request can merge, with no bypass actors, so a commit reaches main only when its automated status checks pass.


    Enough for a badge!

    Prior to a commit being accepted, the project's CI/CD pipelines MUST run at least one automated test suite to ensure the changes meet expectations. [OSPS-QA-06.01]
    Automated tests should be run prior to every merge into the primary branch. The test suite should be run in a CI/CD pipeline and the results should be visible to all contributors. The test suite should be run in a consistent environment and should be run in a way that allows contributors to run the tests locally. Examples of test suites include unit tests, integration tests, and end-to-end tests.

    The CI workflow runs the race-enabled Go test suite on every pull request; that job is a required status check on the default branch, so no commit is accepted without the automated tests passing.


    Enough for a badge!

    When the project has made a release, the project documentation MUST include design documentation demonstrating all actions and actors within the system. [OSPS-SA-01.01]
    Include designs in the project documentation that explains the actions and actors. Actors include any subsystem or entity that can influence another segment in the system. Ensure this is updated for new features or breaking changes.

    docs/design.md documents the system's actors (operator, tool, origin, asset CDN, Xdebug) and every action the tool takes, including a sequence diagram of the warm flow and a trust-boundary description. It is linked from the README's Design section.


    Enough for a badge!

    When the project has made a release, the project documentation MUST include descriptions of all external software interfaces of the released software assets. [OSPS-SA-02.01]
    Document all software interfaces (APIs) of the released software assets, explaining how users can interact with the software and what data is expected or produced. Ensure this is updated for new features or breaking changes.

    The released software is a command-line binary; all Go packages are internal, so it exposes no importable API. Its sole external interface, the CLI, is documented in the README: every command, flag, argument, the stdin list source, the stdout report format, exit statuses, and environment variables.


    Enough for a badge!

    When the project has made a release, the project MUST perform a security assessment to understand the most likely and impactful potential security problems that could occur within the software. [OSPS-SA-03.01]
    Performing a security assessment informs both project members as well as downstream consumers that the project understands what problems could arise within the software. Understanding what threats could be realized helps the project manage and address risk. This information is useful to downstream consumers to demonstrate the security acumen and practices of the project. Ensure this is updated for new features or breaking changes.

    SECURITY.md's "Security assessment" section identifies the most likely and impactful security problems for a tool that fetches URLs with credentials (credential disclosure, sending credentials to unintended hosts, cleartext transmission, sensitive data in logs, supply-chain compromise, and unintended debugger activation) and states how the design mitigates each.


    Enough for a badge!

    The project documentation MUST include a policy for coordinated vulnerability disclosure (CVD), with a clear timeframe for response. [OSPS-VM-01.01]
    Create a SECURITY.md file at the root of the directory, outlining the project's policy for coordinated vulnerability disclosure. Include a method for reporting vulnerabilities. Set expectations for how the project will respond and address reported issues.

    SECURITY.md's "Reporting a Vulnerability" section defines a private reporting channel, a first-response timeframe of one business day (Mon-Fri), and a coordinated process: fixes are worked out with the reporter, who is credited and decides on public disclosure.


    Enough for a badge!

    The project documentation MUST provide a means for private vulnerability reporting directly to the security contacts within the project. [OSPS-VM-03.01]
    Provide a means for security researchers to report vulnerabilities privately to the project. This may be a dedicated email address, a web form, VCS specialized tools, email addresses for security contacts, or other methods.

    Met on the contact form documented in SECURITY.md, namely https://osinet.fr/contact


    Enough for a badge!

    The project documentation MUST publicly publish data about discovered vulnerabilities. [OSPS-VM-04.01]
    Provide information about known vulnerabilities in a predictable public channel, such as a CVE entry, blog post, or other medium. To the degree possible, this information should include affected version(s), how a consumer can determine if they are vulnerable, and instructions for mitigation or remediation.

    SECURITY.md's "Published advisories" section states that fixed vulnerabilities are published as GitHub Security Advisories on the repository, feeding the public GitHub Advisory Database and OSV, and are recorded under a Security heading in the CHANGELOG.
