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

Rescanned at commit b938c00f0870, unchanged since the check below.

NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    src/index.ts, line 123 async fetch(request: Request, env: Env, ctx: ExecutionContext) {

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    src/index.ts, line 123 async fetch(request: Request, env: Env, ctx: ExecutionContext) {

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 75 # dotenv environment variable files

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    worker-configuration.d.ts, line 1 /* eslint-disable */

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.
