Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to bvm-core@1.1.43. The same advisory and Firewall decision cover these 2 recorded versions: 1.1.42, 1.1.43. - Avoid installing bvm-core@1.1.43. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% dist/index.js in bvm-core@1.1.43 imports child\_process and issues fetch() calls to the hardcoded host https://bvm-core.nexsail.top at the top of the bundled module, alongside a secondary fetch to registry.npmmirror.com. The combination — a lookalike domain that mirrors the package name on an unrelated TLD, module-load-time network calls, and child\_process usage in the same bundle — is the fingerprint of an install/import-time beacon and command execution channel, not a legitimate SDK call. The package name resembles established \`bvm\` version-manager tooling but the code routes traffic to an author-controlled host on nexsail.top rather than to any documented registry or vendor endpoint. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 5 - **Peer dependencies:** 0 - **Development dependencies:** 5 - **Published dependency-graph edges:** 5 ### Published dependency entries - @oven/bun-darwin-aarch64 1.3.11 (OptionalDependency) - @oven/bun-darwin-x64 1.3.11 (OptionalDependency) - @oven/bun-linux-aarch64 1.3.11 (OptionalDependency) - @oven/bun-linux-x64 1.3.11 (OptionalDependency) - @oven/bun-windows-x64 1.3.11 (OptionalDependency) ## Package metadata - **Package:** bvm-core - **Ecosystem:** npm - **Version:** 1.1.43 - **License:** MIT - **Version published:** 2026-07-16T09:23:44.741Z - **Package first seen:** 2026-07-16T02:04:07.908Z - **Package last seen:** 2026-07-16T19:45:09.798Z - **Known versions:** 4 - **Latest version:** 1.1.43 - **Appeal under review:** No - **Description:** Bun version manager with reliable public-mirror downloads for mainland China, cross-platform switching, and runtime isolation. - **Author:** EricLLLLLL - **Maintainers:** lei.liao - **Keywords:** bun, bvm, bun-version-manager, version-manager, bun-nvm, nvm-for-bun, nvm-alternative, fnm-alternative, bun-version-switching, bun-runtime-manager, bun-multi-version, bun-shims - **Artifact files:** 11 - **Artifact unpacked size:** 167,001 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]()
