React Security Stinger

Where this skill's files are

Every path below (guides/, references/, scripts/) is relative to the folder that contains this SKILL.md. In Claude Code that folder is ${CLAUDE_SKILL_DIR}. If that text was not replaced with a real path, find the folder yourself (for example with Glob for **/react-security-stinger/SKILL.md) and use it as <skill> in every command.

Purpose

Find, confirm, and report the security weaknesses that are specific to React application code, for the security dimension of an /audit-my-code run (contract 1.0). It covers React 18 and 19 client components, server rendering, and React Server Components with Server Functions where they run outside Next.js (Vite with @vitejs/plugin-rsc, React Router RSC and Framework Mode, Waku, Parcel, RedwoodSDK, hand-rolled react-server-dom-* servers). It produces 02-security/findings-react-security-wasp-drone.jsonl, metrics-react-security-wasp-drone.json, and notes-react-security-wasp-drone.md, with every finding backed by evidence, and changes nothing in the audited repository.

When to use

• The orchestrator's stack routing says react (or nextjs, for the client half) and dispatches react-security-wasp-drone
• "Security audit this React app", "check our Vite SPA for XSS", "are we exposed to React2Shell", "is CVE-2025-55182 patched here"
• "Audit our Server Functions", "are our 'use server' actions safe", "do we leak secrets in the bundle"
• Reviewing an AI-built React app (Lovable, Bolt, v0, Cursor, Claude Code scaffolds) for the usual generator mistakes

When not to use

• Next.js server surfaces (Server Actions, route handlers, middleware or proxy, next.config, Next.js version advisories): nextjs-security-stinger
• Generic OWASP pass, repository-wide and git-history secret scanning, dependency advisories outside React: security-stinger
• Svelte or SvelteKit: sveltekit-security-stinger. Non-JavaScript backends: polyglot-security-stinger
• Fixing the issues: this Stinger is research-only and never edits the audited repository; remediation planning is the mario tier's job
• Architecture review without a security question: react-stinger

Procedure

1. Read the arming line and the contract (audit-my-code-stinger/references/audit-contract.md). Write only inside <workspace>/02-security/ and only to your per-source files.
2. Scope and versions: run guides/00-scoping-and-version-detection.md. It runs scripts/react_version_check.py (lockfiles against the advisory table) and scripts/sink_scan.py (candidate lines), maps the stack per path, and decides which guides apply.
3. XSS and SSR injection: guides/01-xss-and-injection-sinks.md.
4. RSC and Server Functions (when present outside Next.js): guides/02-rsc-and-server-functions.md.
5. Secrets and data exposure: guides/03-secrets-and-data-exposure.md.
6. Auth, routing, client trust: guides/04-auth-routing-client-trust.md.
7. Supply chain and AI-generated patterns: guides/06-supply-chain-and-ai-patterns.md.
8. Write findings, metrics, and notes: guides/05-writing-findings.md. Every candidate becomes a finding, a "Not confirmed" note, or a dismissed count; never a finding without evidence.
9. Return the verdict, finding counts by severity, every coverage cap, and the list of raw files written.

Critical Directive

• You must read all files and context contained within your skill.
• In the event your core knowledge does not provide sufficient guidance you must make every attempt to search the internet, related knowledge base documentation files, and other available resources to supplement your knowledge prior to proceeding with your task.
• Additional related skills can be found here:
  • nextjs-security-stinger - Next.js Server Actions, route handlers, middleware, config, and Next.js version advisories.
