Nosql Injection

yaklang/hack-skills
2.4k installs1.6k stars
Summary

This is the playbook you need if you're testing anything with MongoDB, CouchDB, or Redis on the backend. It's not SQL injection with a fresh coat of paint. The entire attack surface is different: you're injecting query operators like $ne and $gt instead of breaking out of quotes, using $regex for blind character extraction instead of UNION, and exploiting JSON parsing quirks in Express or PHP to turn password fields into objects. Covers authentication bypass, blind data exfiltration via regex oracle, $where JavaScript injection, and even CouchDB's often-exposed admin API on port 5984. Includes a Python template for automating character-by-character password extraction. Most pentesters who only know SQL patterns completely miss these.

app-observability

grafana/skills

Get RED metrics + service maps + frontend RUM + AI/LLM monitoring out of Grafana Cloud — Application Observability (`traces_spanmetrics_*` from OTel traces, p50/p95/p99 latency, exemplar-to-trace, traces-to-logs / profiles), Frontend Observability with the Faro Web SDK (Core Web Vitals, session replay, `pushError`, React + router integration, `TracingInstrumentation` for browser → backend trace correlation), and AI Observability via OpenLIT (token / cost / latency, GPU, hallucination + toxicity evals). Use when standing up APM for a service, wiring an Alloy OTLP receiver + forwarding to Cloud, instrumenting a React frontend for RUM, debugging why service-map edges are missing, monitoring LLM cost drift, or correlating a frontend error to its backend trace — even when the user says "set up APM", "show service map", "monitor browser perf", "session replay", "RUM SDK", or "watch our OpenAI bill" without naming App / Frontend / AI Observability.
