AI Security Review
scanned 11d ago · by lpm-firewall-aiThe inspected risk is an explicit user-invoked agent configuration change, which warrants a warning under the agent capability policy. The manifest and reviewed source do not establish an automatic install-time attack or credential exfiltration.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user runs `pai worker fallback on`.
Impact
Future Claude Code processes use the configured provider until the user turns fallback off. No confirmed credential theft or covert mutation was identified.
Mechanism
The command writes the provider endpoint, token, and model settings into the Claude Code settings file; the matching off command restores saved settings.
AI rationale
The inspected risk is an explicit user-invoked agent configuration change, which warrants a warning under the agent capability policy. The manifest and reviewed source do not establish an automatic install-time attack or credential exfiltration.
Evidence
dist/program-DSETzrWg.mjsdist/fallback-B5svk75f.mjs
Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The explicit `pai worker fallback on` command changes Claude Code settings for future processes.
- The fallback uses the configured provider endpoint and token, then writes them into Claude Code settings.
- The notification hook sends only its message to ntfy.sh when NTFY_TOPIC is configured; no credential forwarding is shown.
Evidence against
- The manifest has no install, preinstall, or postinstall hook; its prepublishOnly command is a build and worker command.
- The flagged settings mutation is exposed through an explicit CLI command with matching off and status actions.
