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

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    src/transports/http.test.ts, line 22 const sseRes = await fetch(`${url}/`, {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .dockerignore, line 45 .env

  • OBFUSCATION_ENCODED_BLOB Low

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

    src/links/encode.test.ts, line 58 const LANDING_B64 = 'Y2hhcnQgYmFyLXZlcnRpY2FsIHsKICB0aXRsZSA9ICJFIGlzIHRoZSBtb3N0IGZyZXF1ZW50IGxldHRlciBpbiBFbmdsaXNoIgogIGRlc2NyaXB0aW9uID0gIkhvdyBvZnRlbiBlYWNoIGxldHRlciBhcHBlYXJ

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.
