 - **Repository Access**: The action can only be triggered by users with write access to the repository
 - **Bot User Control**: By default, GitHub Apps and bots cannot trigger this action for security reasons. Use the `allowed_bots` parameter to enable specific bots or all bots
+  - **⚠️ Allowed bots are not checked for repository permissions.** A bot that matches an entry does **not** need to be installed on your repository or have write access. On a **public repository**, external parties — including GitHub Apps created by anyone — may be able to trigger workflow events such as opening issues, commenting, or reviewing pull requests. If your workflow listens on those events and `allowed_bots` is set to `'*'`, any such App can invoke this action with a prompt it controls.
+  - Prefer an explicit list over `'*'`
+  - Only list App names you trust
+  - If you need `'*'`, scope workflow `permissions:` to the minimum required
 - **⚠️ Non-Write User Access (RISKY)**: The `allowed_non_write_users` parameter allows bypassing the write permission requirement. **This is a significant security risk and should only be used for workflows with extremely limited permissions** (e.g., issue labeling workflows that only have `issues: write` permission). This feature:
   - Only works when `github_token` is provided as input (not with GitHub App authentication)
   - Accepts either a comma-separated list of specific usernames or `*` to allow all users
