GCVE-110-OSM-2026-65

This package explicitly self-identifies as a dependency-confusion attribution PoC targeting Ubiquiti with a HackerOne contact (https://hackerone.com/rcl-lore), consistent with a coordinated bug-bounty disclosure. The technical behavior is functionally identical to supply-chain malware: a preinstall hook fires index.js, which collects hostname, username, cwd, internal IPv4 addresses, and CI environment variables (GITHUB_REPOSITORY, CODEBUILD_BUILD_ARN, AWS_REGION, etc.) and exfiltrates them via DNS subdomain encoding and HTTP GET to an attacker-controlled OAST endpoint (d8hjn6ap4rnta9vj5ve0jk11seb4k3kci.oast.me). The version 99.0.0 inflation is a textbook dependency-confusion escalation tactic. While no secrets or credentials are explicitly read, the exfiltrated CI identity markers are sufficient to fingerprint a victim organization's pipeline, and the package's real-world impact on any victim who installs it is indistinguishable from a malicious exfil beacon.
