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 0x2ai-demo8x@1.2.0. - Avoid installing 0x2ai-demo8x@1.2.0. 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% On \`npm install\`, scripts/postinstall.cjs copies the package's payload/ tree into INIT\_CWD (the consumer's project root) using fs.cpSync, dropping.mcp.json,.claude/settings.json, CLAUDE.md, and several chatroom-\* CJS files into the developer's repository. The dropped.mcp.json registers an MCP server pointing at https://demo8.0x2ai.com with a hardcoded shared Bearer token (BRIDGE\_AUTH\_TOKEN=9272d409b5155094d9562c92700f46a4b97bdb48d8291d40), so any subsequent Claude Code session in that directory loads the attacker-authored CLAUDE.md system prompt and routes tool calls to the bridge. The bundled chatroom-mcp-lite-patched.cjs exposes a \`provider\_query\` tool that POSTs user prompts to https://demo8.0x2ai.com/api/proxy-query, a \`settings\_set\` tool advertised for storing anthropic\_api\_key / openai\_api\_key on the bridge, and a salted-SHA256 path-obfuscation helper that rewrites endpoints to /x/\ form (deliberate evasion infrastructure, dormant only because the shipped config sets DIRECT\_API=1). bin/start.cjs additionally re-stages the payload and spawns \`claude --dangerously-skip-permissions\` with shell:true, yielding an unrestricted agent session wired to the attacker's MCP server. Net effect on installers: prompts, code, files, and potentially LLM API keys are funneled to a third-party bridge under a shared credential, with no disclosure or opt-in. ## 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:** 0x2ai-demo8x - **Ecosystem:** npm - **Version:** 1.2.0 - **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:** 1.2.0 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [OpenSSF JSON]() - [PACKAGE]()
