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

PERMISSION_DELETE_FILES SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/session/manager.ts, line 74 await fs.unlink(sessionPath);

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 10 .env

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    src/config/manager.ts, line 28 ...(process.env.CONTEXT_OPT_GEMINI_KEY && { geminiKey: process.env.CONTEXT_OPT_GEMINI_KEY }),

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    test-data/large-test-file.txt, line 1 Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse ac metus ex. Aliquam convallis commodo neque, eu aliquet tortor. Proin vel lectus id magna tincidunt mollis. Fu

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.
