Node Aws Security Audit
Perform comprehensive security audits on Node.js, JavaScript, and TypeScript codebases.
Compatibility: Not stated.
Grade D
Two or more Medium findings, or a High finding. Only try it in a sandbox.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
Rescanned at commit b9afd31a8cd4, unchanged since the check below.
NETWORK_HOST_FROM_INPUT SECRETS_PATH_CREDENTIAL
Why this grade
- NETWORK_HOST_FROM_INPUT Medium
A file takes a URL or endpoint as input and has no fixed host list.
install.sh, line 3
# Usage: bash <(curl -fsSL https://raw.githubusercontent.com/Grenguar/node-aws-security-audit/main/install.sh) - SECRETS_PATH_CREDENTIAL Medium
Mentions a credential store path (~/.ssh, id_rsa, .npmrc, .aws/credentials, credentials.json, .netrc).
SKILL.md, line 109
find . -maxdepth 1 \( -name ".env*" -o -name "tsconfig.json" -o -name ".eslintrc*" -o -name ".npmrc" \) 2>/dev/null; \
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.
