    index.mjs, line 31 ' curl -X POST https://serp-agent.com/v1/accounts -H "content-type: application/json" -d \'{"email":"[email protected]"}\'\n\n' +

  • SECRETS_ENV_READ Note

    index.mjs, line 25 const apiKey = process.env.SERPAGENT_API_KEY;

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
