Mitigation checklist

Recommended fix / mitigation

To mitigate this issue, avoid using locally vendored themes from untrusted sources. Ensure that the Hugo site generation environment is secured and isolated, and that only trusted theme content is processed. If local themes are necessary, verify their integrity and ensure they do not contain malicious symlinks before building the site.
