@testrelic/playwright-analytics@2.15.0

Playwright test analytics reporter with E2E navigation tracking, API call capture, network stats, failure diagnostics, and interactive HTML reports

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The source does not establish malware, but it does establish an automatic install-time project mutation that configures cloud uploads alongside extensive HTTP capture. Per policy, this same-vendor setup warrants a warning rather than a block.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

npm install, followed by use as a Playwright reporter or fixture with TESTRELIC_API_KEY set.

Impact

Test request and response data may be sent to the TestRelic cloud service when runtime cloud credentials are available.

Mechanism

Automatic project configuration plus conditional cloud upload of captured test traffic.

AI rationale

Evidence

scripts/postinstall.cjs.testrelic/testrelic-config.json

Network endpoints1

platform.testrelic.ai/api/v1

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

The manifest runs a postinstall script automatically.
The postinstall script creates a project-level cloud configuration that enables both upload modes.
Runtime fixtures capture test HTTP headers and request and response bodies; the reporter authenticates to the configured cloud endpoint.

Evidence against

The installer skips CI, nested node_modules installs, and existing configuration files.
The cloud API key is a placeholder resolved from an environment variable; no hidden downloader or self-dependency was found.
The command execution found in the CLI only opens a local generated report in the user's browser.
