The script uses curl to query the cloud instance metadata service via the nip.io wildcard-DNS resolver (169.254.169.254.nip.io/latest/meta-data/), base64-encodes the response, and POSTs it over plain HTTP to a hardcoded canarytokens.com endpoint (http://canarytokens.com/terms/7dc94zmd3so67n5vbz5bxmt7v/contact.php). On installers running on AWS/GCP/Azure hosts with IMDS reachable, this leaks IAM role identifiers and, on IMDSv1, temporary cloud credentials to a third-party canary endpoint at install time. The tarball ships no source files; the manifest and its preinstall hook are the entire payload. The scope name and package name are consistent with a dependency-confusion / SSRF canary probe targeting an internal namespace.\n\n---\n\nCredit: OpenSSF (source)","public_affected_ranges":["= 1.1.0"]}],"null_published_at":"2026-11-01T01:45:40.756Z","source_updated_at":"2026-09-21T03:30:33.000Z","source_disclosed_at":"2026-09-21T03:30:27.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-01T00:59:39.394Z"}],"next_cursor":null,"snapshot_revision":"42594"}
