What the code does
We read the source, 17 h ago · rules 3dff92dd89df
A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.
fs.writeFileSync(savePath, Buffer.from(base64, 'base64'));
What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
crontab -e → add: 0 */4 * * * npx feishu-user-plugin keepalive --all >> /tmp/feishu-keepalive.log 2>&1
try { execSync(`node ${_p.join(__dirname, t + '.js')}`, { stdio: 'inherit' }); }
const dir = path.join(FIX_ROOT, hash);
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
A tool parameter here reaches a dangerous call
That is not a flaw by itself — but it is where things go wrong when it is not the job. We re-read this code on every release. Watch it and you hear from us the day another one appears.
