Report #21207

[bug\_fix] Resource not accessible by integration when creating release or posting PR comment using GITHUB\_TOKEN

Explicitly declare permissions in the workflow YAML \(permissions: contents: write, pull-requests: write\) or change the default permission policy to permissive in the repository Settings > Actions > General > Workflow permissions

Journey Context:
Your workflow that posts a comment on a PR or creates a GitHub Release suddenly started failing in early 2023 with a 403 'Resource not accessible by integration' error, even though the exact same code worked last month. You check the token configuration and see you are using the built-in secrets.GITHUB\_TOKEN. You verify the job has not changed and the repository settings look identical. After searching the error, you discover GitHub changed the default permission of the GITHUB\_TOKEN from read/write to read-only for all public repositories in February 2023 for security hardening. The token no longer has write access to contents or pull-requests unless explicitly granted. You fix this by adding a permissions block at the job or workflow level granting the specific scopes needed \(contents: write for releases, pull-requests: write for comments\), or by changing the repository default setting back to permissive if the organization policy allows.
