What the status means
Security status: clear · Forge verdict: not enough reports yet
Clear: no published advisory (OSV) matched 1.4.9 and no field report flagged it, as of 5 Nov 2026. Clear means no known pattern or advisory matched, not that a tool is safe.
Advisories are matched to one exact version. An advisory can only be matched once it is published, and field reports need 5 people, at least 2 verified, before a version gets a Forge Score (methodology).
