OpenSSF/OSV advisory MAL-2026-4729 confirms this npm version as malicious. On \`npm install\`, scripts/postinstall.js fetches a \`companion-\-\\` binary from \`github.com/palmthree-studio/whiteboard-agent/releases/download/nightly/...\` — a mutable release tag (not pinned to package version 1.4.24) with no SHA/signature verification — chmods it 0755, and in non-TTY installs (CI, agent, scripted environments) spawns it detached... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-06-30T15:00:00.099Z - **Finished:** 2026-06-30T15:00:00.099Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. 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 whiteboard-agent@1.4.24. The same advisory and Firewall decision cover these 2 recorded versions: 1.4.23, 1.4.24. - Avoid installing whiteboard-agent@1.4.24. 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% On \`npm install\`, scripts/postinstall.js fetches a \`companion-\-\\` binary from \`github.com/palmthree-studio/whiteboard-agent/releases/download/nightly/...\` — a mutable release tag (not pinned to package version 1.4.24) with no SHA/signature verification — chmods it 0755, and in non-TTY installs (CI, agent, scripted environments) spawns it detached. The same non-TTY path generates an \`admin\` account with a random 16-hex password, starts the companion HTTP server on 127.0.0.1:3001 with \`COMPANION\_LOCALHOST\_BYPASS=1\`, then spawns \`cloudflared tunnel --url http://localhost:3001\`, publishing the local server to a public \`\*.trycloudflare.com\` URL. The combination is install-time-triggered remote ingress: anyone who learns or guesses the tunnel URL can reach the companion API on the installer's host without authentication beyond the random credential, which is itself generated and stored locally without user notification. README documents \`wendy start\` performing tunnel exposure interactively, but does not warn that \`npm install\` itself does this silently in non-interactive environments — the typical CI / build-agent / container scenario. Independently, the \`nightly\` mutable-tag binary fetch means every install (and reinstall/update) pulls whatever bytes are at that tag at that moment; a stolen publish credential or a future malicious push compromises every installation without any version bump. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 1 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 1 ### Published dependency entries - cloudflared ^0.7.1 (Dependency) ## Package metadata - **Package:** whiteboard-agent - **Ecosystem:** npm - **Version:** 1.4.24 - **License:** MIT - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 2 - **Latest version:** 1.4.24 - **Appeal under review:** No - **Description:** Wendy — the companion CLI for Whiteboard.
