ci(release): publish a signed packslip with each release - #807
Conversation
The release now carries `packslip.sigstore.json`: one signed document listing every archive's sha256 and sha512, the executable inside it, the shared objects it loads from the host, and the build provenance of each file, signed keylessly with this workflow's OIDC identity. An installer verifies a download against the identity `github.com/jdx/fnox` rather than against a signing key this project would have to hold and rotate. `fnox usage` runs against the freshly built Linux binary and its output is uploaded as `fnox.usage.kdl`, listed as a `cli-spec` resource. From that a consumer generates completions, a man page, and documentation with its own copy of usage, so nothing of fnox's has to run on the machine it is installed on. See https://packslip.dev.

💡 Result:
In the jdx/fnox repository, the GitHub Actions workflows are configured to use explicit authentication tokens for release and release-related operations [1][2]. Specifically, the FNOX_GH_TOKEN is used as a repository secret to provide the necessary permissions for release automation tools like release-plz, which need to push git tags and release branches [2]. The GITHUB_TOKEN is a built-in token provided by GitHub Actions that generally has scoped, read-only permissions by default, but is explicitly configured with higher permissions (such as contents: write) in specific job contexts when required [1]. The workflow_dispatch trigger is utilized across various CI/CD workflows (including ci.yml, release-plz.yml, and release.yml) to allow maintainers to manually trigger these processes [1][2][3]. Key details regarding the workflow configuration include: - Security Hardening: Recent changes (such as those associated with the adoption of zizmor for security analysis) have hardened these workflows by explicitly scoping token permissions, defaulting to permissions: {}, and disabling credential persistence in actions/checkout [1]. - Token usage: The release-plz workflow, for example, sets GITHUB_TOKEN to the value of the FNOX_GH_TOKEN secret when running its release logic to ensure it has the required write access for git operations [2]. - Workflow Dispatch: The use of workflow_dispatch allows for manual intervention, testing, or retries of the release pipeline, often requiring input parameters like the version tag [1][4]. In summary, FNOX_GH_TOKEN is an elevated personal access token (or equivalent) stored as a secret to handle authenticated git operations, while GITHUB_TOKEN is used as the standard, environment-provided runner token, with both being carefully managed via workflow-level permission settings to adhere to the principle of least privilege [1][2].

Sensitive Data Exposure (CWE-522): Insufficiently Protected Credentials
Reachability: External · Exploitability: Difficult
Do not expose release credentials to bin/fnox.
GITHUB_TOKEN is set from secrets.FNOX_GH_TOKEN at workflow scope. A manually dispatched run can execute code from the selected ref, so the extracted binary can read and exfiltrate this token. Clear GITHUB_TOKEN, GH_TOKEN, and FNOX_GH_TOKEN for this command, and restrict release runs to protected refs.

site:cli.github.com/manual/gh_release_create --target target commit GitHub CLI
💡 Result:
In the GitHub CLI (gh), the --target flag is primarily used with the gh release create command to specify the target branch or full commit SHA for automatic tag creation [1]. When using gh release create, if a matching git tag does not exist, the CLI creates one from the latest state of the default branch by default; providing a --target value allows you to point to a specific branch or commit SHA instead [1]. The gh pr create command does not use a --target flag to set a commit; instead, it uses the --base flag to specify the target branch for a pull request. Example usage for gh release create: gh release create v1.0.0 --target [1]
Citations:
Bind the release tag to the signed commit.
On workflow_dispatch from a non-default ref, gh release create can create a missing tag from the default branch, while packslip records github.sha in the manifest. Add --target "$GITHUB_SHA" and fail before signing if the remote tag does not resolve to $GITHUB_SHA.
