📝 SummarySummary by CodeRabbit
WalkthroughThe push email workflow now targets branch pushes, keeps concurrent runs active, limits job execution to five minutes, and uses a pinned SMTP notification action with the existing SMTP configuration and message content. ChangesPush email notification workflow
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The email workflow should remove its unnecessary repository-read permission before merge to avoid exposing private source contents if the third-party action is compromised. Poem

15-15: 🎯 Functional CorrectnessNo change is required for branch deletions.
GitHub Actions routes branch deletions to the
deleteevent, not thepushtrigger. Therefore,on.push.branches: ['**']does not run this job for a deletion.

GitHub Actions workflow permissions contents read GITHUB_TOKEN third-party action official documentation
💡 Result:
GitHub provides the GITHUB_TOKEN as a short-lived, repository-scoped authentication token for workflows [1][2]. To maintain security and follow the principle of least privilege, you should explicitly define the minimum permissions required by your workflow or individual jobs using the permissions key [3][4]. When using third-party actions, it is a recommended security practice to restrict these permissions [5][6]. By default, the GITHUB_TOKEN may have broader access than necessary; you can override this by setting the permissions key at the top level of your workflow or within specific jobs [7][4]. If you define the permissions key, any permission not explicitly listed is set to none [2][4]. For example, to grant only read access to repository contents, use the following configuration [2][8]: permissions: contents: read For maximum security, some security guides recommend starting with permissions: {} at the workflow level to disable all permissions by default, and then adding only the specific, required permissions for each job [6][9]. Key points for managing GITHUB_TOKEN permissions: - Default Settings: Repository and organization administrators can set the default permissions for the GITHUB_TOKEN in repository or organization settings (e.g., restricted to read-only contents) [7][2]. - Workflow Override: The permissions defined in your workflow file override the repository-level default settings [7][4]. - Third-Party Actions: Because third-party actions can access the GITHUB_TOKEN context, granting broad permissions poses a supply chain risk [5][10]. Always audit third-party actions, pin them to a specific commit SHA rather than a tag, and grant them only the minimum necessary permissions [5][6][9]. - Read vs Write: Specifying read automatically includes read access; specifying write grants both read and write access [4][8].

Remove the unnecessary repository-read token permission.
The pinned composite action only downloads and executes the SMTP binary. It does not access repository contents or the GitHub API. Set permissions: {}. If the action is compromised, contents: read can otherwise expose private repository contents.
