Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
Rescanned at commit 6c374ae6c77b.
NETWORK_HOST_FROM_INPUT SECRETS_PATH_CREDENTIAL
Why this grade
- NETWORK_HOST_FROM_INPUT High
A file takes a URL or endpoint as input and has no fixed host list.
ui/src/pages/ApiExplorer.tsx, line 348
const call = opts.length ? `fetch(${JSON.stringify(r.href)}, {\n${opts.join('\n')}\n})` : `fetch(${JSON.stringify(r.href)})`; - SECRETS_PATH_CREDENTIAL Medium
Mentions a credential store path (~/.ssh, id_rsa, .npmrc, .aws/credentials, credentials.json, .netrc).
scripts/npm-publish.sh, line 107
# literal values. An .npmrc line such as ${NPM_TOKEN} referencing an unset
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.
If you think this grade is wrong, email [email protected] with the entry link and your evidence. We aim to acknowledge within two working days and decide within seven. If we confirm an error, we aim to correct it within 24 hours of confirming it. These are aims, not guarantees.
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.
