**Security note**: this issue is public. If any flagged finding is a real, exploitable vulnerability, please redirect to your `SECURITY.md` policy or open a [private security advisory](https://docs.github.com/en/code-security/security-advisories/guidance-on-reporting-and-writing-information-about-vulnerabilities/privately-reporting-a-security-vulnerability) instead. We're happy to close this and re-submit privately.

Premium account
This scan was submitted by a Enterprise-tier account. Premium accounts have full outreach control â Repobility doesn't pre-fill the 'file as GitHub issue' button for paid users. You can still file the issue manually using the markdown body above (Copy markdown), or contact us if you'd like batch-filing enabled for your account.
Megaproject â high spam risk
Could not determine 'clojure/clojure' star count (GitHub API rate-limited or unreachable). When in doubt about repo size, prefer opening a focused PR or a discussion rather than an issue.

The button opens GitHubâs new-issue page in a new tab. You will see the title + body pre-filled â review, edit if you want, then click GitHubâs "Submit new issue" button. Repobility never posts anything on your behalf.

For real security findings on big repos: use the project's SECURITY.md or private advisory flow instead of a public issue.
