The same advisory and Firewall decision cover these 2 recorded versions: 5.0.0, 5.0.1. - Avoid installing panrouter@5.0.1. 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% panrouter is advertised as a 'Claude Code router' but on default invocation (\`panrouter\` with no arguments) it (a) installs and rewrites the user's Claude Code configuration so that ANTHROPIC\_BASE\_URL points at a local proxy, and (b) launches a detached Node process running relay\_client.cjs that opens a persistent WebSocket to wss://jiuling.xyz/ws. The relay registers the host using hostname+pid as nodeId and processes inbound JSON messages: any message containing a \`command\` field is passed verbatim to child\_process.execSync with operator-supplied cwd and timeout, giving the operator of jiuling.xyz a fully-controlled remote shell on every installer's machine. The relay maintains itself via exponential-backoff reconnect and a 45s heartbeat watchdog. On Windows, the shipped tray-daemon.ps1 adds an HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Run entry named 'PanRouter' for autostart and respawns relay\_client.cjs every 5 seconds if missing, ensuring persistence across reboots. Independently, server.mjs and relay\_client.cjs hardcode all Claude Code requests to be forwarded to https://opencode.ai/zen/v1/chat/completions with Authorization: 'Bearer public', remapping any user-selected model to 'deepseek-v4-flash-free'. cli.mjs writeConfig() overwrites ~/.claude/settings.json so that ANTHROPIC\_BASE\_URL=http://127.0.0.1:50816 and ANTHROPIC\_AUTH\_TOKEN=public, causing all Claude prompts the user issues — which routinely contain source code and secrets — to be silently routed through opencode.ai under a shared anonymous 'public' identity rather than the user's own Anthropic account. ## 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:** panrouter - **Ecosystem:** npm - **Version:** 5.0.1 - **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:** 5.0.1 - **Appeal under review:** No - **Description:** PanRouter 客户端 v5.0 — 自愈式组网，单例保护，指数退避重连，实时状态推送 - **Maintainers:** jiuling - **Artifact files:** 7 - **Artifact unpacked size:** 58,649 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]()
