AI Security Review

scanned 4d ago · by lpm-firewall-ai

The manifest has no install lifecycle hook, and the inspected configuration behavior is tied to explicit CLI installation. Telemetry is opt-in, and the reviewed scanner-flagged paths did not establish a concrete attack.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

A user invokes the package's install command; telemetry additionally requires MULTI_AGENT_TELEMETRY=1.

Impact

No confirmed harmful effect was identified in the inspected behavior.

Mechanism

The installer configures agent-specific local files and settings. With telemetry enabled, it posts package and environment metadata to the package's telemetry endpoint.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest exposes a CLI entrypoint and has no npm install lifecycle hook.
Installation telemetry runs only when MULTI_AGENT_TELEMETRY is set to 1 and sends package and environment metadata.
The installer configures local agent directories and a secret-detection hook as part of its explicit install command.
The reviewed autopilot, doctor, graph, citation-checking, and MCP-registration targets support local pipeline setup and maintenance.

135 `-w` cannot be used to read a secret this store may hold. It prints any value

136 containing a byte outside plain printable ASCII as BARE HEX with no marker,

137 which is indistinguishable from a secret that is itself hex - and 40-character

138 hex API tokens are exactly what lives here. Guessing from the shape would

139 corrupt them. `-g` marks the encoded form with an `0x` prefix, so the decision

140 is read off the output instead of inferred:

141

142 multi-line value -> password: 0x6C696E65310A6C696E6532 "line1\\012line2"

Secret Pattern

144

145 Two shapes, measured rather than assumed:

146 - `0x<HEX>` present -> the hex is authoritative; a quoted trailer may follow

147 or may be absent entirely (an all-non-ASCII value prints hex only).

148 - no `0x` -> the value sits between the first and last double quote. Inner

149 quotes are NOT escaped by `security` (`he"llo` prints as `"he"llo"`), so

150 first-to-last is the correct span and unescaping would be wrong.

151

152 The secret is parsed in-process and returned to the caller. It is never

153 logged, never placed in an exception message, and never passed as an argv

154 element.

177 Trailing newlines are stripped, which is what the `-w` path did before and

178 what every consumer already assumes: a newline on the end of a token is an

179 artifact of pasting it, and it breaks an HTTP header the moment it survives.
