  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    server_sse.py, line 51 SUPABASE_KEY = os.environ.get("SUPABASE_ANON_KEY")

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    german-cities.json, line 1 [{"p":"10958","n":"-LABO- Landesamt für Bürger- und Ordnungsangelegenheiten","s":"Land Berlin","la":52.5045,"ln":13.3895},{"p":"10898","n":"ABK Allgemeine Beamten Bank AG","s":"Lan

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.
