Don't report security vulnerabilities in public issues, pull requests, or discussions.
Report them privately through GitHub: open the repository's Security tab and choose Report a vulnerability, or go directly to https://github.com/anyone-oslo/pages/security/advisories/new.
The principles in CONTRIBUTING.md apply here too: describe what you observed, give minimal steps you actually ran, and include raw output. Report what you verified; the maintainers will assess the impact.
