@pmate/cli@0.29.9
CLI utilities for the pMate project
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package is a first-party pmate CLI with no install-time attack, but command handlers forward the saved session token to an unrestricted operator-configured base URL. That conditional credential exposure is a dangerous capability, not a hidden exfiltration payload.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Running a pmate subcommand that calls request() after the user or environment sets a non-default base URL.
Impact
If the operator points the base URL at an unrelated host, the existing service session token is exposed to that host. Default use stays on the pmate API.
Mechanism
readRequiredSession loads the token from the local session store, and request() fetches baseUrl plus a path with that token as a Bearer header without checking the host.
AI rationale
The package is a first-party pmate CLI with no install-time attack, but command handlers forward the saved session token to an unrestricted operator-configured base URL. That conditional credential exposure is a dangerous capability, not a hidden exfiltration payload.
Evidence
dist/index.js~/.pmate/session.json
Network endpoints1
agent-api.pmate.chat
Decision evidence
public snapshotAI called this Suspicious at 74.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The published bin and main entry are dist/index.js. package.json has a prepare build script and no preinstall, install, or postinstall hook.
- Command handlers load the saved pmate session token and send it as a Bearer token to a base URL taken from a CLI flag or environment variable, falling back to a pmate host, with no host allowlist before fetch.
- main() runs only when dist/index.js is the process entrypoint, so importing the package does not start those requests.
Evidence against
- Defaults point at first-party pmate.chat APIs and the send path is a user-run CLI command.
- No eval, remote payload fetch, install-time agent-config writes, or self-dependency lifecycle chain was found.
- The session file is stored under the user home .pmate directory with mode 0600.
