Why this grade

    src/emoji-map.ts, line 111 const response = await fetch(teamsEcsConfigUrl);

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    src/emoji-map.ts, line 111 const response = await fetch(teamsEcsConfigUrl);

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    package-lock.json, line 1 {

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.
