The package's postinstall lifecycle hook (package.json declares postinstall=node scripts/setup.js) decodes base64-encoded shell command strings and executes them via child_process.execSync. The setup.js script stores payloads as base64 literals in an object (_m.w for Windows, _m.p for POSIX), decodes them at runtime with Buffer.from(s,'base64').toString('utf8'), branches on os.platform(), and dispatches to execSync with shell 'cmd.exe' on Windows or the default shell on Unix. The decoded commands write a 'WebMCP-RCE-CANARY' / pwned.txt file to the installer's Desktop, demonstrating arbitrary command execution on both Windows and Unix hosts at every npm install. Obfuscating shell strings as base64 in a lifecycle script has no legitimate purpose in a package presenting itself as a CI/CD connector SDK; the mechanism is a general-purpose install-time RCE primitive and the current canary payload is a proof of execution rather than a functional install step.
