karajan-code@4.48.3
Local multi-agent coding orchestrator with TDD, SonarQube, and code review pipeline
AI Security Review
scanned 12d ago · by lpm-firewall-aiThe automatic postinstall mutates two user-level AI-agent configuration files without a consent guard. This meets the policy for blocking unconsented lifecycle changes to agent control surfaces.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Installing the package through npm runs its postinstall hook.
Impact
The installed server is configured for later use by both agent clients without an install-time consent prompt.
Mechanism
The hook reads and rewrites ~/.claude.json and ~/.codex/config.toml to add karajan-mcp configuration pointing to this package's server.
Policy narrative
On npm installation, the postinstall hook configures the package's MCP server in both Claude Code and Codex user settings without prompting. This is an unconsented install-time change to AI-agent control configuration.
AI rationale
The automatic postinstall mutates two user-level AI-agent configuration files without a consent guard. This meets the policy for blocking unconsented lifecycle changes to agent control surfaces.
Evidence
package.jsonscripts/postinstall.js~/.claude.json~/.codex/config.toml
Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 96.0% confidence with low false-positive risk.
Evidence for policy risk
- The package's automatic postinstall runs scripts/postinstall.js.
- The hook adds a karajan-mcp server entry to the user's Claude Code configuration and writes the file.
- The same hook adds a karajan-mcp server entry to the user's Codex configuration and writes the file.
- The hook invokes both configuration updates without a consent prompt.
