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

PERMISSION_SHELL_UNDECLARED INSTALL_LIFECYCLE_HOOK SECRETS_PATH_CREDENTIAL

Why this grade

  • PERMISSION_SHELL_UNDECLARED Medium

    Runs shell commands that the manifest or description does not mention.

    ee/rag-core/src/routes/rag-upload.ts, line 217 await fs.unlink(file.filepath).catch(() => undefined);

  • INSTALL_LIFECYCLE_HOOK Medium

    A package install hook (preinstall, install, postinstall or prepare) runs a script.

    package.json, line 24 prepare

  • SECRETS_PATH_CREDENTIAL Medium

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

    ee/rag-core/src/fs-write.ts, line 164 /^(\.env.*|.*credentials?.*|.*secrets?.*|.*\.(pem|key|p12|pfx|keystore)|id_(rsa|dsa|ecdsa|ed25519).*|\.npmrc|\.netrc|authorized_keys|passwd|shadow)$/i;

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.

    /** Injectable child-process spawn - defaults to `child_process.spawn`. Tests supply a fake. */

  • Install and update

    Concern

    runs a script at install time.

    INSTALL_LIFECYCLE_HOOK

    package.json, line 24

    prepare
