Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/utils/credentials-writer.ts, line 121 fs.unlinkSync(tmpFile);

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    package.json, line 60 @github/keytar

  • NETWORK_NO_FIXED_HOST Low

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

    src/auth/device-auth-flow.ts, line 44 const response = await fetch(`https://${config.tenant}/oauth/device/code`, {

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    src/auth/device-auth-flow.ts, line 44 const response = await fetch(`https://${config.tenant}/oauth/device/code`, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/tools/applications.ts, line 471 get file. Do NOT read, open, or echo any .env file (.env, .env.local, etc.) before or

  • SECRETS_ENV_READ Note

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

    src/commands/run.ts, line 115 if (process.env.AUTH0_TOKEN && !process.env.AUTH0_DOMAIN) {

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    NOTICE, line 1 NOTICE

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Concern

    can delete files.

    PERMISSION_DELETE_FILES

    src/utils/credentials-writer.ts, line 121

    fs.unlinkSync(tmpFile);

    src/utils/env-credentials.ts, line 528

    fs.unlinkSync(tmpPath);

  • Install and update

    Concern

    dependencies are not pinned.

    INSTALL_UNPINNED

    package.json, line 60

    @github/keytar

  • Network

    Concern

    can reach a host that is not written as a fixed address. can reach api.smithery.ai. The description does not name that host.
