NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED OBFUSCATION_FILE_OVER_READ_CAP
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
docs/design/wp-cache-provenance/architecture.md, line 280
Side effects: one plug-in request per goal fetch (see the interface below). - SECRETS_PATH_DOTENV Low
Mentions a .env file.
src/mcp/server.rs, line 2296
.env("TMPDIR", tmp_dir) - PERMISSION_SHELL_DECLARED Note
Runs shell commands, and the manifest or description says so.
scripts/check-artifacts.sh, line 106
listing = subprocess.run(["git", "ls-files"], capture_output=True, text=True) - OBFUSCATION_FILE_OVER_READ_CAP Note
A file was over the read cap and was not fully read.
src/mcp/analysis.rs, line 1
use std::collections::{BTreeMap, BTreeSet};
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.
