Compatibility: Not stated.
Grade B
Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
Rescanned at commit 1d20ba973986, unchanged since the check below.
NETWORK_NO_FIXED_HOST SECRETS_PATH_UNCONFIRMED 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.
cli/src/api.ts, line 27
const res = await fetch(`${this.baseUrl}${path}`, { - SECRETS_PATH_UNCONFIRMED Low
The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.
cli/.gitignore, line 1
.DS_Store - OBFUSCATION_FILE_OVER_READ_CAP Note
A file was over the read cap and was not fully read.
worker/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.
