Audit repositories for insecure defaults and hardening gaps across debug modes, exposed admin and actuator surfaces, CORS, security headers, cookie flags, TLS, containers, IaC, default credentials, and reverse proxies.
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
## Scope & Objectives Detect misconfiguration findings that arise from insecure defaults left unchanged or hardening controls never applied. This module covers ten classes: 1. **Debug/prod confusion** — debug flags, verbose error pages, stack traces and environment dumps reaching clients. 2. **Exposed admin/debug/actuator endpoints** — Spring Boot Actuator, Django debug toolbar, Laravel Telescope/_ignition, phpMyAdmin/Adminer, swagger-ui, monitoring consoles, `.git`/`.env` served from webroot, directory listings. 3. **CORS misconfiguration** — origin reflection with credentials, wildcards, `null` origin, overbroad subdomain matching, per-route divergence. 4. **Missing/weak security response headers** — CSP, HSTS, `X-Content-Type-Options`, `X-Frame-Options`, Referrer-Policy, Permissions-Policy. 5. **Cookie/session flags** — `Secure`, `HttpOnly`, `SameSite` per framework session store; name prefixes `__Host-` (forces Secure, `Path=/`, no Domain) and `__Secure-` where the framework supports them — enforce-by-construction instead of flag-checking. 6. **TLS configuration** — legacy protocols, weak cipher strings, disabled certificate validation between internal services. …

How to install
mdr add as-foss/aegis-skills/aegis-configuration-hardening@sha256:7210bed0da073fd3The line at the top of this page pins the label git:20260826.9702747, 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.
