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 weavedb-sdk-base@0.21.1. - Avoid installing weavedb-sdk-base@0.21.1. 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% package.json declares \`"preinstall": "./bin/install-deps"\`, pointing at a ~976KB packed Linux x86-64 ELF binary shipped in the tarball (sha256 36abd242ddaa27f0160c539377a0e92cf781c1695137850acc87e3892b436d36). The package self-describes as a pure-JavaScript decentralized-DB SDK, so a native Linux helper has no documented purpose during install. No source code (.c/.cc/.rs/binding.gyp), no node-gyp or prebuild-install machinery, and no hash/signature verification accompanies the binary; its bytes are packed (fragmented, non-contiguous strings characteristic of UPX or a custom packer), preventing review. Extracted strings reveal HTTP/1.1, POST, DELETE, https://, USERPROFILE, LIBBPF (eBPF), PTRACE, and TLS/cipher routines — capabilities entirely inconsistent with a JavaScript SDK and consistent with a credential-harvest / surveillance / RCE payload. On \`npm install weavedb-sdk-base\` on Linux, this binary executes with the installer's UID before dependency resolution completes, giving the publisher arbitrary native code execution on the installer's machine. \#\# Source: google-open-source-security (146faaf0d97c6a533a969bc3f3f117811f9317dc865ed4ab37f1679842ddeaae) This package was compromised as part of the IronWorm campaign. This campaign executes a malicious binary payload during installation via a preinstall hook. The payload is a Rust-built infostealer that targets developer environments, scanning for and harvesting credentials related to cloud providers, object storage, databases, source-control, package registries, and AI developer tools. It also targets cryptocurrency wallets, specifically injecting a malicious JavaScript hook into the Exodus desktop wallet to capture passwords and recovery phrases. Furthermore, the malware exhibits worm-like behavior by stealing GitHub and NPM credentials to push malicious updates to the victim's repositories and publish trojanized packages, and it uses an eBPF-based kernel rootkit to hide its processes and network connections on Linux systems. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** weavedb-sdk-base - **Ecosystem:** npm - **Version:** 0.21.1 - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 1 - **Latest version:** 0.21.1 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [ARTICLE]() - [ARTICLE]()
