OpenSSF/OSV advisory MAL-2026-4675 confirms this npm version as malicious. The package advertises itself as a local-only static analyzer (README: "Runs locally. Your code never leaves the machine" and "What's never transmitted: source code, file contents"). The actual implementation in src/cli.mjs and src/server.mjs walks the target directory, reads file contents — explicitly including any file whose name starts with \`.env\` (cli.mjs line 74: \`if (!SCAN\_EXTENSIONS.has(ext)... ## 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 supership-scan@1.0.0. - Avoid installing supership-scan@1.0.0. 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% The package advertises itself as a local-only static analyzer (README: "Runs locally. Your code never leaves the machine" and "What's never transmitted: source code, file contents"). The actual implementation in src/cli.mjs and src/server.mjs walks the target directory, reads file contents — explicitly including any file whose name starts with \`.env\` (cli.mjs line 74: \`if (!SCAN\_EXTENSIONS.has(ext) &&!entry.startsWith('.env')) continue;\`) — and POSTs the full file map to \`https://supership.crestsystems.ai/scan/\\` (cli.mjs line ~99, server.mjs line ~108). The local scanner module is not invoked on the free path; uploading is unconditional across all tiers. The MCP server variant exposes \`scan\_directory\` and \`scan\_code\` tools to AI coding agents (Claude Code, Cursor, Windsurf), so an agent invoking these tools silently ships the user's repository — including production secrets in \`.env\`, \`.env.production\`, \`.env.local\` (DATABASE\_URL, API keys, JWT secrets, cloud credentials) — to the author's endpoint without consent. This is the canonical silent-relay pattern: caller-supplied data (source code + secrets) is hard-coded to flow to an author-controlled destination while marketing claims the opposite. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 1 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 1 ### Published dependency entries - @modelcontextprotocol/sdk ^1.12.0 (Dependency) ## Package metadata - **Package:** supership-scan - **Ecosystem:** npm - **Version:** 1.0.0 - **License:** Apache-2.0 - **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:** 1.0.0 - **Appeal under review:** No - **Description:** Predeploy security scanner for the agent economy. 80+ vulnerability patterns.
