Megaproject â high spam risk
Could not determine 'tukaani-project/xz' 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.
Already filed
15/31 findings (48%) on this scan are already flagged as test-file, won't-fix, or suppressed. The scan is too noisy to file as a single issue. Curate down to specific actionable findings, or address the FP source first.

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.
