SECRETS_PATH_DOTENV SECRETS_ENV_READ
Why this grade
- SECRETS_PATH_DOTENV Low
Mentions a .env file.
README.md, line 56
Copy `sample.env.env` to `.env` (or export the variables another way) and update only the providers you plan to use. Never commit the populated `.env` file. - SECRETS_ENV_READ Note

password=os.getenv("BROWSER_USE_PROXY_PASSWORD"),
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.
