Report #35272

[bug\_fix] Resource not accessible by integration \(403\) when creating releases, packages, or pushing to protected branches using GITHUB\_TOKEN

Explicitly declare write permissions in the job or workflow YAML using the \`permissions\` key \(e.g., \`permissions: contents: write\` for releases, or \`packages: write\` for GHCR\). This overrides the default read-only setting that GitHub applied to all repositories starting February 2023.

Journey Context:
The developer merges a PR and expects the release job to publish a GitHub Release. Instead, the job fails with a 403 error "Resource not accessible by integration" when the \`softprops/action-gh-release\` action attempts to POST to the API. The developer checks the repository secrets, verifies that \`GITHUB\_TOKEN\` is present, and even tries regenerating it. They examine the workflow logs and notice a subtle line: "Token permissions: read-only". Searching this phrase leads them to a GitHub Blog post from February 2023 announcing that new repositories and existing ones would default to restrictive permissions. The developer realizes the fix isn't in the repository settings UI \(though it could be changed there globally\), but in the workflow file itself for portability. They add \`permissions: contents: write\` to the specific job, re-run the failed job, and the release publishes successfully because the token now carries the explicit write scope.

environment: GitHub Actions workflows on github-hosted runners \(ubuntu-latest, windows-latest, etc.\) in repositories created after February 2023 or organizations with restrictive default settings. Affects workflows creating releases, commenting on PRs, or pushing to protected branches. · tags: github_token permissions default read-only 403 changelog-2023 contents write · source: swarm · provenance: https://github.blog/changelog/2023-02-02-github-actions-updating-the-default-github\_token-permissions-to-read-only/
