Check common security risks in application code (SQLi, XSS, secrets, open redirect).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Pattern declaration
Primary pattern: Reviewer
Secondary patterns: Inversion
Why: セキュリティチェックはチェックリスト型評価が主だが、セキュリティ無関係の変更では実行を止めるゲートが必要
## Guidance
- Look for string-concatenated queries or unsafe ORM calls; require parameterization.
- Flag unescaped HTML sinks (`dangerouslySetInnerHTML`/`innerHTML`) and missing sanitization.
- Catch secrets or tokens hardcoded in code; prefer environment/config inputs.
- Ensure input validation and authz/CSRF/error handling paths exist without leaking sensitive detail.
- Open redirect: a return URL may pass a same-host check by a server-side parser (e.g. PHP `parse_url`), then reach `Location` / `redirect()` / `href`. Check that values containing `\` are rejected before that check.
- PHP `parse_url('http://evil.example\\@self.example/', PHP_URL_HOST)` returns `self.example`.
- Browsers (WHATWG URL) treat `\` as `/` and navigate to `evil.example`.
- If the value is decoded again after the check (double encoding, a later `urldecode`), reject `%5C` as well.

How to install
mdr add s977043/river-review/Baseline Security Checks@sha256:4443950ba2b53580The line at the top of this page pins the label v0.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
