`r5d-browser start --auto-update` enables automatic client updates for this environment and state directory. The setting persists; `--no-auto-update` disables it. The client checks the authenticated environment's selected release once a minute and stages
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe configurable destination is not bound to the credential's intended service, creating a concrete conditional credential-exposure risk. The inspected package has no lifecycle hook, so blocking is not supported.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Running the CLI with the start command.
Impact
A token can be exposed if an operator-configured HTTPS endpoint is untrusted.
Mechanism
The client selects a base URL from options, environment, or configuration, reads a token, and posts it as a bearer credential.
AI rationale
The configurable destination is not bound to the credential's intended service, creating a concrete conditional credential-exposure risk. The inspected package has no lifecycle hook, so blocking is not supported.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The manifest exposes a JavaScript CLI entry point.
- The start command initializes the personal browser connection.
- The connection accepts a configurable HTTPS origin and obtains a token from options, configuration, or environment variables.
- Requests send that token as a bearer credential to the configured origin without a destination allowlist.
- The Chrome launcher refuses the user's daily-driver Chrome profile.
- The browser runtime can execute supplied JavaScript in the controlled page.
Evidence against
- No npm lifecycle hook is declared in the inspected manifest.
- The credential transfer occurs only when the user invokes the start command and configures a connection.
