Graded by PlugVetRubric v2

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

INSTALL_REMOTE_SCRIPT SECRETS_PATH_CREDENTIAL

Why this grade

  • INSTALL_REMOTE_SCRIPT Medium

    Fetches a script from the network and runs it (a pipe to a shell, or an install hook with a URL).

    projects/second-brain/config/scripts/setup-vault-mac.sh, line 100 curl -fsSL https://claude.ai/install.sh | bash

  • SECRETS_PATH_CREDENTIAL Medium

    Mentions a credential store path (~/.ssh, id_rsa, .npmrc, .aws/credentials, credentials.json, .netrc).

    projects/aws-serverless/config/scripts/verify.sh, line 6 # profile ~/.aws/credentials 의 프로파일 이름 (키는 여기에만 둔다)

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.

If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.

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

    Serious

    install fetches a script from the network.

    curl -fsSL https://claude.ai/install.sh | bash

  • Network

    Concern

    can reach raw.githubusercontent.com. The description does not name that host. can reach github.com. The description does not name that host. can reach a host that is not written as a fixed address.
