Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

Rescanned at commit 57b45eb97b1d.

SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED NETWORK_LOCALHOST OBFUSCATION_FILE_CAP_REACHED

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    docs/run/authorization.md, line 398 cp env.example .env

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    src/Client/Transport/StdioTransport.php, line 218 $process = proc_open(

  • NETWORK_LOCALHOST Note

    Calls localhost only.

    examples/server/stateless-lifecycle/server.php, line 48 * curl -sS http://127.0.0.1:8000/ \

  • OBFUSCATION_FILE_CAP_REACHED Note

    The 400 file cap was reached before every file was read.

    src/Server/Stateless/RequestStateCodec.php, line 1 <?php

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.
