AI Security Review

scanned 12d ago · by lpm-firewall-ai

Source inspection found a gated, allowlisted user-memory append capability, but no install-time mutation or concrete attack behavior. This guarded agent configuration capability warrants a warning rather than a publish block.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

A caller invokes the server memory-append operation.

Impact

The selected agent memory file can be changed, which may affect later agent context.

Mechanism

The operation checks thread capability, chooses `CLAUDE.md` or `AGENTS.md`, and appends the supplied text under the resolved Claude configuration directory.

AI rationale

Evidence

dist/bin.mjs

Decision evidence

public snapshot

AI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package exposes `p4c` through `dist/bin.mjs`; `package.json` shows no lifecycle script.
A server operation appends caller-supplied text to user-scope `CLAUDE.md` or `AGENTS.md`, after checking thread capability and an allowlist.
The UI describes the append as a memory-file operation; this is an explicit capability, not evidence of install-time mutation.
The flagged runtime adapter code resolves the installed `node-pty` helper; the Bun adapter is terminal-process support.

Evidence against

The manifest has no preinstall, install, or postinstall hook.
The memory append is invoked through a server operation and limited to two named memory files; the inspected code does not establish an unconsented install-time write.
No credential exfiltration or unrelated external recipient was established by the inspected excerpts.
