fix(ci): grant the label job pull-requests write (release-1.12.0) - #14591
Conversation
Every "Label PR" run has failed since #14540 -- 67 successes and no failures before it, 16 failures after (the successes since are runs where the job's `if:` skips it, e.g. merge_group and bot PRs): POST /repos//issues/14588/labels 403 Resource not accessible by integration #14540 added a `permissions:` block to this workflow. Before that there was none, so it inherited the repository default, which includes pull-requests write. Labelling a *pull request* needs that scope: the `issues` permission only covers real issues even though the REST path is `/issues/{n}/labels`. GitHub says so in the response itself: x-accepted-github-permissions: issues=write; pull_requests=write Also unblocks Namchee/conventional-pr in the same workflow, which cannot post its report under a read-only pull-requests scope. (cherry picked from commit 9454ac4)
WalkthroughThe conventional labels workflow changes its pull-request permission from read-only to write access. ChangesWorkflow permissions
Estimated code review effort: 1 (Trivial) | ~2 minutes Merge Risk: 🔵 Low · up to The workflow now grants pull-request write access more broadly than necessary, increasing the impact of a compromised or misbehaving action in jobs that only need read access. The change is localized and mergeable with explicit owner awareness or follow-up to scope permissions per job. Possibly related PRs

Namchee/conventional-pr v0.16.0 GitHub action permissions issues write pull-requests write comments
💡 Result:
To resolve permissions issues when using Namchee/conventional-pr (including v0.16.0) for actions like commenting or labeling, you must ensure the GitHub Action has the necessary write permissions [1][2]. 1. Required Write Access: The action requires write access to your repository to perform operations such as closing pull requests, adding labels, or posting comment reports [1][2]. If you are using the default GITHUB_TOKEN, you must explicitly define permissions in your workflow file [3]: permissions: pull-requests: write 2. Handling Forks and Security: The action is primarily designed for internal environments and not for execution on forked repositories [4][5]. When running in an environment where pull requests may originate from forks, using the default pull_request event can lead to permission restrictions. To address this, it is recommended to change the workflow trigger from pull_request to pull_request_target [4][6]. This shifts the execution context to the base repository, allowing the workflow to access required repository secrets and permissions safely [4][6]. 3. Personal Access Tokens (PAT): If you require advanced features like the edit validation report, be aware that the default GITHUB_TOKEN does not have the necessary user scope [4][5]. In such cases, you must generate and provide a personal access token (PAT) with appropriate permissions via the access_token input [4][1]. 4. Security Best Practices: Avoid granting excessive write permissions to workflows triggered by pull_request events from untrusted sources to prevent potential security exploits [4][6]. Using pull_request_target requires caution; ensure your workflow does not inadvertently expose repository secrets or allow malicious code execution by validating the content of the pull request [4][6].

GitHub Actions GITHUB_TOKEN permissions issues write pull-requests write addLabels removeLabel createComment REST API
💡 Result:
To resolve GITHUB_TOKEN permissions issues when using the REST API for actions like creating pull requests, adding labels, or creating comments, you must explicitly define the required permissions in your workflow YAML file [1][2]. GitHub Actions now defaults the GITHUB_TOKEN to read-only permissions [3][1]. If your workflow attempts a write operation without explicit configuration, it will fail with a 403 Forbidden error, often described as "Resource not accessible by integration" [1][4]. To fix this, add a permissions block to your workflow or specific job [1][5]: permissions: pull-requests: write issues: write For specific operations, ensure you grant the correct scope: 1. Pull Requests: Use pull-requests: write to create or update pull requests [1][2]. 2. Comments: Use issues: write to create comments on issues or pull requests (since pull request comments are handled under the issues API) [1][2]. 3. Labels: Use issues: write to add or remove labels [2]. Key Considerations: - Least Privilege: Only grant the permissions strictly necessary for your job [6][1]. Any permission not explicitly included in the block will be set to none [2]. - Forked Repositories: Pull requests from public forks are a special case; the GITHUB_TOKEN will remain read-only for these workflows, regardless of your permissions configuration, to prevent unauthorized access to secrets [7][2]. - Troubleshooting: You can inspect the X-Accepted-GitHub-Permissions header in your API responses to determine exactly which permissions are required for a specific endpoint [4][8]. - Limitations: The GITHUB_TOKEN is scoped exclusively to the repository where the workflow is running. If you need to interact with external repositories, you must use a Personal Access Token (PAT) or a GitHub App installation access token instead [1][4].

site:docs.github.com/en/rest/issues/issues add labels pull request permissions issues write
💡 Result:
To add labels to a pull request or issue on GitHub, a user must have at least push access to the repository [1]. While the Triage role is noted as having permission to edit issues [1], the specific ability to manage labels is explicitly tied to push access in the repository's API documentation [1]. Without this required level of access, any attempts to set or change labels will be silently ignored or dropped by the system [1]. This requirement applies to both the initial creation of an issue or pull request and any subsequent updates [1].

site:docs.github.com GitHub Actions GITHUB_TOKEN pull-requests read GraphQL repository pullRequest query
💡 Result:
Yes, you can use the GITHUB_TOKEN in a GitHub Actions workflow to query pull request data via the GraphQL API [1][2]. To successfully perform a pullRequest query, the GITHUB_TOKEN must have the necessary permissions granted in your workflow configuration [3][2]. Key considerations: Permissions Configuration: You must explicitly set the permissions for the GITHUB_TOKEN in your workflow YAML file to include at least read access to pull requests [3][4]. You can do this at the job or workflow level [3][4]: permissions: pull-requests: read Authentication: The GITHUB_TOKEN is a GitHub App installation access token automatically provided to your workflow [5]. You can use it as a bearer token in your GraphQL requests [1][2]. For example, when using the GitHub CLI (gh) within a step, you can pass it via an environment variable [1][2]: env: GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} run: | gh api graphql -f query=' query { repository(owner: "owner", name: "repo") { pullRequest(number: 1) { title state } } } ' Scope Limitations: The GITHUB_TOKEN is scoped strictly to the repository where the workflow is running [5][6]. If you need to access pull request data from other repositories or organizations, you will need to use a different authentication method, such as a GitHub App installation access token or a personal access token [6][7]. If you encounter errors during your GraphQL request, ensure that the token has the correct scope and that your query is formatted correctly for the GitHub GraphQL API [8][9].

Set validate-pr to contents: read and pull-requests: read. Set label to issues: write. Remove workflow-level issues: write and pull-requests: write. The configured action does not close, label, or post reports, while the label job uses the Issues API for label changes.
