AI Security Review
scanned 11d ago · by lpm-firewall-aiNo confirmed malicious attack surface was established. The risky primitives are runtime server/CLI features aligned with a universal server package.
Static reason
One or more suspicious static signals were detected.
Trigger
User runs the srvx CLI or imports srvx adapters at runtime.
Impact
No hidden exfiltration, persistence, install-time execution, or destructive behavior identified.
Mechanism
user-invoked server startup, local entry loading, static serving, and curl-like fetch mode
Rationale
Static inspection shows a legitimate universal server/CLI implementation; dynamic imports, child process use, environment reads, and network fetch behavior are user-invoked and package-aligned. No install-time code, hardcoded exfiltration, credential harvesting, persistence, destructive action, or AI-agent control-surface mutation was found.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for block
Evidence against
- package.json has bin entry and dev/prepack/release scripts, but no install/postinstall/prepare lifecycle hook.
- bin/srvx.mjs only imports dist/cli.mjs and invokes main with docs/issues metadata.
- dist/cli.mjs child_process.fork restarts the same srvx bin with watch/env-file/import args for serve mode.
- dist/cli.mjs fetch mode uses user-supplied URL/path and headers; no hardcoded exfiltration endpoint.
- dist/loader.mjs dynamic import loads explicit/discovered local server entry files as core package functionality.
- Adapters implement server/runtime request handling and static file serving; no credential harvesting, persistence, or destructive writes found.

Cross File Remote Execution Context
Source spawns a local helper that also contains network and dynamic execution context; review data flow before blocking.
