springboot-security

springboot-security is a skill for Claude Code, Codex from Luohaothu/everything-codex. It costs 40 tokens per session (1,009 once invoked), scanned A, original, MIT.

A security guide for Java Spring Boot services covering login and permissions, input validation, CSRF protection, secrets, HTTP headers, rate limits, and dependency safety. CSRF is an attack that tricks a logged-in browser into sending an unwanted request.

In plain words
What is it for?
Use it when adding authentication, protecting endpoints, validating requests, handling credentials, or reviewing Spring Boot security settings.
Why use it?
It helps prevent unauthorised access, unsafe input handling, secret exposure, common web attacks, and vulnerable dependencies.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

springboot-security scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Spring Boot 安全审查

在添加身份验证、处理输入、创建端点或处理密钥时使用。

身份验证

  • 优先使用无状态 JWT 或带有撤销列表的不透明令牌
  • 对于会话,使用 httpOnly、Secure、SameSite=Strict cookie
  • 使用 OncePerRequestFilter 或资源服务器验证令牌
@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);
    if (header != null && header.startsWith("Bearer ")) {
      String token = header.substring(7);
      Authentication auth = jwtService.authenticate(token);
      SecurityContextHolder.getContext().setAuthentication(auth);
    }
    chain.doFilter(request, response);
  }
}

授权

  • 启用方法安全:@EnableMethodSecurity
  • 使用 @PreAuthorize("hasRole('ADMIN')") 或 @PreAuthorize("@authz.canEdit(#id)")
  • 默认拒绝;仅公开必需的 scope

输入验证

  • 在控制器上使用带有 @Valid 的 Bean 验证
  • 在 DTO 上应用约束:@NotBlank、@Email、@Size、自定义验证器
  • 在渲染之前使用白名单清理任何 HTML

SQL 注入预防

  • 使用 Spring Data 存储库或参数化查询
  • 对于原生查询,使用 :param 绑定;切勿拼接字符串

CSRF 保护

  • 对于浏览器会话应用程序,保持 CSRF 启用;在表单/头中包含令牌
  • 对于使用 Bearer 令牌的纯 API,禁用 CSRF 并依赖无状态身份验证
http
  .csrf(csrf -> csrf.disable())
  .sessionManagement(sm -> sm.sessionCreationPolicy(SessionCreationPolicy.STATELESS));

密钥管理

  • 源代码中不包含密钥;从环境变量或 vault 加载
  • 保持 application.yml 不包含凭据;使用占位符
  • 定期轮换令牌和数据库凭据

安全头

http
  .headers(headers -> headers
    .contentSecurityPolicy(csp -> csp
      .policyDirectives("default-src 'self'"))
    .frameOptions(HeadersConfigurer.FrameOptionsConfig::sameOrigin)
    .xssProtection(Customizer.withDefaults())
    .referrerPolicy(rp -> rp.policy(ReferrerPolicyHeaderWriter.ReferrerPolicy.NO_REFERRER)));

速率限制

  • 在昂贵的端点上应用 Bucket4j 或网关级限制
  • 记录突发流量并告警;返回 429 并提供重试提示

依赖项安全

  • 在 CI 中运行 OWASP Dependency Check / Snyk
  • 保持 Spring Boot 和 Spring Security 在受支持的版本
  • 对已知 CVE 使构建失败

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

springboot-security is a skill published in the GitHub repository Luohaothu/everything-codex (25 stars, last pushed 2mo ago), licensed MIT. It adds 40 tokens to every session and 1,009 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
