Comprehensive OWASP-aligned security guidance across six standards - Top 10 (2021) for web apps, ASVS 5.0, MASVS v2.1.0 for mobile, API Security Top 10 (2023), Kubernetes Top 10 (2022), and the Agentic Applications 2026 edition for AI/LLM. Use for security reviews, vulnerability audits, secure auth/crypto/access-control implementation, Kubernetes manifest hardening, and LLM/agent prompt-injection defense - including indirect requests like "is this login flow secure?", "review this endpoint…

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.

## Section 1: OWASP Top 10 (2021)

The OWASP Top 10 represents the most critical security risks in web applications.

### A01: Broken Access Control
**Detection:** URLs with direct ID references (`/user/1234/orders`); client-side only enforcement; missing authorization checks.
**Mitigation:** Enforce server-side authorization for every sensitive operation; verify user ownership of resources; implement default-deny principle.
**Example:**

How to install

The exact contents, by fingerprint

mdr add davila7/claude-code-templates/owasp-security@sha256:92c9604aa21999f4

The line at the top of this page pins the label git:20260706.31fc2b5, 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.
