Restrict pull-requests: write to the comment job.
These permissions apply to every step in the workflow. Artifact downloads, package installation, and Netlify deployment therefore use a write-capable job token, although only the final comment step needs that scope. Set workflow-level permissions: {} and split deployment and commenting into jobs with separate minimal permissions. GitHub supports different token permissions per job. (docs.github.com)

GitHub Actions workflow permissions GITHUB_TOKEN permissions do not affect personal access token secrets GH_TOKEN gh CLI GITHUB_TOKEN environment variable official documentation
💡 Result:
The GitHub Actions workflow permissions block (using the permissions key) strictly governs the permissions granted to the default GITHUB_TOKEN secret [1][2]. These settings do not affect or limit other credentials, such as personal access tokens (PATs) or other GitHub App installation access tokens that you manually provide as secrets [1][3]. When you use the GitHub CLI (gh) in a workflow, you must explicitly provide an authentication token via an environment variable, typically GH_TOKEN [4][5]. While both GITHUB_TOKEN and GH_TOKEN are accepted by the CLI, using GH_TOKEN is the recommended best practice [6][5]. The permissions of the gh CLI operations will be determined entirely by the token provided in the GH_TOKEN variable, regardless of the workflow-level permissions set for the GITHUB_TOKEN [1][6]. If your workflow requires permissions exceeding what is granted to the default GITHUB_TOKEN, you must use a separate credential (like a PAT or a different GitHub App token) stored as a secret [1][3]. You should then pass this secret as the GH_TOKEN environment variable for your gh CLI commands [3][7]. Note that when using custom tokens, you are responsible for managing their scope and permissions, as they are not subject to the restricted GITHUB_TOKEN permission settings defined in the workflow YAML [1][2]. Additionally, be aware that standard tools like actions/checkout may automatically configure git authentication using the GITHUB_TOKEN by default [8]. If you intend to use a different token for git operations, you may need to configure the action (e.g., setting persist-credentials: false) to prevent the default token from taking precedence [8].

Reduce the workflow token permissions.
The website checkout, git push, and gh pr create use secrets.GH_TOKEN, not the workflow token. Set the job permissions to contents: read and remove contents: write and pull-requests: write.

Scope the cross-repository PAT to individual steps.
The job-level GITHUB_TOKEN exposes secrets.GH_TOKEN to npm install and every later step. A compromised dependency or command could read and exfiltrate a token that can write to asyncapi/community.
Remove the job-level environment variable. Pass secrets.GH_TOKEN directly to the required checkout and github-script steps, and set GH_TOKEN only on the gh pr create step. Keep persisted credentials only on the community checkout because the later push requires them.
Proposed token scoping

- GITHUB_TOKEN: ${{ secrets.GH_TOKEN }}

Add a zizmor workflow which scans for common pipeline security issues such as:
harden
update-docs-in-website.ymlworkflowAdd
permissions: {}at workflow level with minimal job-level scopes(contents: write, pull-requests: write) to fix excessive-permissions (without this block, the workflow inherits the write-all permissions of the parent)
Set persist-credentials: false on the generator checkout since it is
read-only; keep it true on the website checkout for git push
Replace embedded-token push URL with git push origin HEAD to prevent
token exposure in logs and process listings (template-injection)
Move github.sha expansions into env vars to keep shell steps
