@sentropic/h2a-runtime@0.97.11
h2a heavy runtime (sessions / k8s / tunnel, node-pty + aws-sdk). Lazily imported by @sentropic/h2a; installed separately.
AI Security Review
scanned 26d ago · by lpm-firewall-aiSource inspection found agent configuration and plugin registration capabilities, but their callers are explicit CLI commands and no install-time hook is declared. The evidence supports a warning for user-invoked agent capability, not a confirmed attack.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user invokes plugin add or enroll with the hook-install option.
Impact
These actions can add package or plugin behavior to agent sessions after user-requested setup.
Mechanism
The plugin command writes MCP configuration, while the enroll command merges Claude session hooks into settings.
AI rationale
Source inspection found agent configuration and plugin registration capabilities, but their callers are explicit CLI commands and no install-time hook is declared. The evidence supports a warning for user-invoked agent capability, not a confirmed attack.
Evidence
dist/plugin.jsdist/enroll.js
Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest exposes the runtime through dist/index.js and has no npm lifecycle scripts.
- The plugin command can register an MCP server in the user's Codex configuration and persist plugin data for remote sessions.
- Claude hook installation is explicitly activated by the enroll --install-hooks CLI option.
- The gateway startup path uses a localhost endpoint and sends session identifiers and workspace ID to it.
- The tmux module imports child-process APIs for the package's stated local and remote session management.
Evidence against
- No inspected source established covert credential collection, unrelated data exfiltration, or unconsented installation-time mutation.
- The agent configuration changes are reached through explicit CLI setup commands.
