OpenSSF flags npm compass-e2e-tests as malicious

1 min readPublished 16 Feb 2026Updated 16 Feb 2026Source: Vulnerability-Lookup (CIRCL) — OpenSSF Package Analysis feed

TL;DR — Remove [email protected] from all environments; OpenSSF Package Analysis flagged it for communicating with a domain associated with malicious activity.

What happened

OpenSSF Package Analysis identified the npm package compass-e2e-tests version 99.0.0 as malicious due to communication with a domain associated with malicious activity.

The suspiciously high version number (99.0.0) is a common pattern in dependency confusion attacks, where attackers publish a high-version package to public registries hoping internal package managers will prefer it over a private package with the same name.

Who is impacted

  • Teams that installed [email protected] in any environment (developer workstations, CI runners, or build containers).

What to do now

  • Search dependency manifests and lockfiles for [email protected] and remove it.
  • Identify where it was installed/executed and treat affected build environments as potentially compromised.
  • Rotate credentials that may have been accessible (CI secrets, npm tokens, cloud keys).
