Deep Next.js security audit (13 to 16, App and Pages Router). Version advisories, proxy and middleware auth, Server Actions, Route Handlers, data exposure, caching, config. Read-only.
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
# Next.js Security Stinger
Designed and built by Legion Code Inc.
## 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 `**/nextjs-security-stinger/SKILL.md`) and use it as the skill directory in every command.
## Purpose
Run the Next.js-specific part of the security dimension of an `/audit-my-code` run. It finds the installed `next` version in every app of the repo and matches it against a normalized table of 61 GitHub Security Advisories (2024 to 2026-09-30, including CVE-2025-29927 and the React2Shell RSC remote code execution CVE-2025-55182), then reviews the places Next.js apps actually break: authorization that lives only in middleware or `proxy.ts`, Server Actions and Route Handlers that are public endpoints without auth or ownership checks, private data passed to Client Components or baked into static and cached output, `NEXT_PUBLIC_` secrets, broad `images.remotePatterns`, dynamic-host rewrites, CSP and header gaps, and…
…Read the whole file at its exact version.
How to install
mdr add legioncodeinc/vibe-coding-tools/nextjs-security-stinger@sha256:c10e87d6a5112f12The line at the top of this page pins the label v1.0.0, 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.
