Knowledge base for all ten OWASP Top 10 (2021) categories with vulnerable and fixed code examples, detection techniques, universal defense patterns, and framework security checklists. Use when reviewing web code for a specific vulnerability class or explaining an OWASP category and its fix.

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

# OWASP Top 10 (2021)

> Comprehensive knowledge base covering all ten OWASP categories with vulnerability patterns, detection techniques, code examples, and framework-specific mitigations.

## Knowledge Base

### A01:2021 - Broken Access Control

Moved from #5 to #1. 94% of applications tested had some form of broken access control. This category covers failures in enforcing that users cannot act outside their intended permissions.

**Vulnerability Patterns**:
- **IDOR (Insecure Direct Object Reference)**: Accessing resources by manipulating identifiers. `GET /api/users/1234/profile` where changing `1234` to `1235` returns another user's data without ownership check.
- **Missing function-level access control**: Admin endpoints accessible to regular users. No middleware/decorator enforcing role checks on sensitive routes.
- **Path traversal**: `GET /files?name=../../../etc/passwd` -- file operations using user-supplied paths without canonicalization and validation.
- **CORS misconfiguration**: `Access-Control-Allow-Origin: *` with `Access-Control-Allow-Credentials: true`, or reflecting the `Origin` header without validation.

How to install

The exact contents, by fingerprint
mdr add hermeticormus/libresecops-claude-code/owasp-top-10@sha256:e19070c66877fdb8

The line at the top of this page pins the label git:20260930.71a2663, 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.
