Graded by PlugVetRubric v2

Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

SECRETS_PATH_CREDENTIAL

Why this grade

  • SECRETS_PATH_CREDENTIAL Medium

    Mentions a credential store path (~/.ssh, id_rsa, .npmrc, .aws/credentials, credentials.json, .netrc).

    src/code_review_agent/security.py, line 4 - Path traversal (review_file reading /etc/passwd, ~/.ssh/id_rsa, etc.)

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.

    - **HIGH**: Blocking `subprocess.run` in async function - now runs in `asyncio.to_thread`.

    CHANGELOG.md, line 75

    - `review_commit` now spawns `git show` via `subprocess.Popen` and wraps `communicate()` in `asyncio.wait_for`. On `TimeoutError` or `CancelledError` the child process is explicitl
