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

PERMISSION_DELETE_FILES INSTALL_UNPINNED NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    vault.py, line 333 os.remove(abs_path)

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    requirements.txt, line 5 mcp>=1.0.0

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    admin_agents.html, line 432 return fetch(path, opts);

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    vault.py, line 441 ".xml", ".svg", ".env", ".gitignore", ".dockerignore",

  • SECRETS_ENV_READ Note

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

    auth_pg.py, line 101 password=os.environ.get("STRATA_PG_PASSWORD", "strata_brain_2026"),

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    demo/strata.db, line 1 SQLite format 3@ *`*.���

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.

  • Install and update

    Concern

    dependencies are not pinned.

    INSTALL_UNPINNED

    requirements.txt, line 5

    mcp>=1.0.0

  • Network

    Concern

    can reach a host that is not written as a fixed address.

    NETWORK_NO_FIXED_HOST

    admin_agents.html, line 432

    return fetch(path, opts);

    admin_agents.html, line 708

    fetch('/admin/api/agents', { headers: { 'X-Admin-Key': key } })
