Spring Security best practices for authn/authz, validation, CSRF, secrets, headers, rate limiting, and dependency security in Java Spring Boot services.
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
# Spring Boot Security Review
Use when adding auth, handling input, creating endpoints, or dealing with secrets.
## When to Activate
- Adding authentication (JWT, OAuth2, session-based)
- Implementing authorization (@PreAuthorize, role-based access)
- Validating user input (Bean Validation, custom validators)
- Configuring CORS, CSRF, or security headers
- Managing secrets (Vault, environment variables)
- Adding rate limiting or brute-force protection
- Scanning dependencies for CVEs
## Authentication
- Prefer stateless JWT or opaque tokens with revocation list
- Use `httpOnly`, `Secure`, `SameSite=Strict` cookies for sessions
- Validate tokens with `OncePerRequestFilter` or resource server
```java
@Component
public class JwtAuthFilter extends OncePerRequestFilter {
private final JwtService jwtService;
public JwtAuthFilter(JwtService jwtService) {
this.jwtService = jwtService;
}
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response,
FilterChain chain) throws ServletException, IOException {
String header = request.getHeader(HttpHeaders.AUTHORIZATION);

How to install
mdr add affaan-m/ecc/springboot-security@sha256:2a605cf9bc3cda7cThe line at the top of this page pins the label git:20260607.4ad5756, 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.
