Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_UNCONFIRMED SECRETS_ENV_READ
Why this grade
- PERMISSION_DELETE_FILES Low
Contains a call that can delete files.
platforms/chaoxing/runner.mjs, line 327
if (fs.existsSync(CODE_FILE)) fs.unlinkSync(CODE_FILE); - NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
platforms/chaoxing/runner.mjs, line 310
const r = await fetch(img.src, { credentials: ' - SECRETS_PATH_UNCONFIRMED Low
The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.
platforms/chaoxing/runner.mjs, line 73
const p = process.env.CHAOXING_PHONE, w = process.env.CHAOXING_PASSWORD; - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.
platforms/chaoxing/runner.mjs, line 73
const p = process.env.CHAOXING_PHONE, w = process.env.CHAOXING_PASSWORD;
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.
