Finds and fixes vulnerabilities in the app you're building.
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.
PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ
Why this grade
- PERMISSION_DELETE_FILES Low
Contains a call that can delete files.
benchmark/tasks/path_traversal_note/check.py, line 28
shutil.rmtree(root, ignore_errors=True) - NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
benchmark/solutions/opus_all22_baseline/ssrf_dns_rebinding.py, line 101
return fetch(url, pinned_ip=pinned) - SECRETS_PATH_DOTENV Low
Mentions a .env file.
.gitignore, line 11
.env - SECRETS_ENV_READ Note
Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

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.
