Graded by PlugVetRubric v2

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

Rescanned at commit 8dd86e9d5af8.

SECRETS_PATH_CREDENTIAL OBFUSCATION_ENCODED_BLOB OBFUSCATION_MINIFIED_PAYLOAD

Why this grade

  • SECRETS_PATH_CREDENTIAL Medium

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

    sample-agentcore-cloudfront-x402-payments/payer-agent/scripts/invoke_gateway.py, line 18 - AWS credentials file (~/.aws/credentials)

  • OBFUSCATION_ENCODED_BLOB Medium

    Contains a long base64 shaped string in a file that should be readable.

    sample-agentcore-cloudfront-x402-payments/payer-infrastructure/bin/app.js, line 64 MappingURL=data:application/json;base64,eyJ2ZXJzaW9uIjozLCJmaWxlIjoiYXBwLmpzIiwic291cmNlUm9vdCI6IiIsInNvdXJjZXMiOlsiYXBwLnRzIl0sIm5hbWVzIjpbXSwibWFwcGluZ3MiOiI7Ozs7Ozs7Ozs7Ozs7Ozs7

  • OBFUSCATION_MINIFIED_PAYLOAD Medium

    Contains a very long line with almost no spaces in a script or style file.

    sample-agentcore-cloudfront-x402-payments/payer-infrastructure/bin/app.js, line 64 MappingURL=data:application/json;base64,eyJ2ZXJzaW9uIjozLCJmaWxlIjoiYXBwLmpzIiwic291cmNlUm9vdCI6IiIsInNvdXJjZXMiOlsiYXBwLnRzIl0sIm5hbWVzIjpbXSwibWFwcGluZ3MiOiI7Ozs7Ozs7Ozs7Ozs7Ozs7

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.
