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 5d0da8aa2a52, unchanged since the check below.
NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
deploy/autodeploy.sh, line 146
if curl -fsS --max-time 5 "$HEALTH_URL" >/dev/null 2>&1; then - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
deploy/autodeploy.sh, line 146
if curl -fsS --max-time 5 "$HEALTH_URL" >/dev/null 2>&1; then - SECRETS_PATH_DOTENV Low
Mentions a .env file.
.env.example, line 1
# Copy to .env and fill in. Every mix command reads it, so credentials are set
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.
