Report #64659

[bug\_fix] Resource not accessible by integration or 403 Forbidden when creating releases, posting PR comments, or pushing to protected branches using GITHUB\_TOKEN

Explicitly declare the required permissions in the workflow YAML using the \`permissions\` key at the workflow or job level \(e.g., \`permissions: contents: write\`, \`pull-requests: write\`\). The root cause is that GitHub changed the default workflow permissions to read-only for new repositories and organizations; GITHUB\_TOKEN now inherits restrictive scopes unless explicitly broadened.

Journey Context:
You set up a workflow that successfully builds artifacts and runs tests, then add a step using \`softprops/action-gh-release\` to create a GitHub Release on tag push. The job fails with \`Resource not accessible by integration\`. You verify the token is present, check repository secrets \(finding none set, assuming the default GITHUB\_TOKEN is used\), and search the error. You find GitHub blog posts from 2021 and 2023 explaining the change to secure-by-default workflow permissions. You navigate to the repository's Settings > Actions > General, confirming "Workflow permissions" is set to "Read repository contents...". Realizing the workflow lacks explicit permissions, you add \`permissions: contents: write\` to the job. The next run succeeds, creating the release. The fix works because the \`permissions\` key dynamically configures the GITHUB\_TOKEN scopes for that specific job, overriding the restrictive default without changing the repository-wide setting.

environment: A GitHub repository created after February 2023 \(or an organization with restrictive defaults enabled\), using GitHub-hosted runners \(ubuntu-latest\), with a workflow triggered by \`push\` tags that attempts to create releases or post PR comments using the default GITHUB\_TOKEN · tags: github-token permissions 403 resource-not-accessible workflow-configuration · source: swarm · provenance: https://docs.github.com/en/actions/security-for-github-actions/security-guides/automatic-token-authentication\#permissions-for-the-github\_token
