GCVE-110-OSM-2026-66

This package self-identifies as a dependency-confusion attribution PoC targeting Ubiquiti's internal pipelines, with a HackerOne contact (rcl-lore) and explicit comments explaining the research methodology. The code does perform real exfiltration — hostname, username, CWD, internal IPv4 addresses, and CI environment variables (GITHUB_REPOSITORY, CODEBUILD_BUILD_ARN, AWS_REGION, etc.) are collected and sent via both DNS-encoded subdomains and HTTP GET to d8hjn6ap4rnta9vj5ve0jk11seb4k3kci.oast.me on preinstall. The inflated version (99.0.0) is a deliberate dependency-confusion tactic. While the author disclaims secret collection and frames this as attribution-only, the exfiltration is functionally real and indistinguishable from malicious dependency confusion from a victim's perspective. Per security-research self-identification criteria this should not be submitted to OSM, but it warrants tracking given the active OAST beacon and CI env var harvesting.
