nosqli

nosqli is a command for coding agents from Awarexone/Agentic-Bug-Hunter. It costs 0 tokens per session (529 once invoked), scanned A, original, MIT.

A scanner for NoSQL injection, an attack where specially shaped JSON or URL parameters change a database query's meaning. It targets databases and tools such as MongoDB and Mongoose, including login endpoints and item queries.

In plain words
What is it for?
Use it to test login or query URLs for operator injection, bracket-style parameters, regular-expression payloads, and time-based $where behaviour. It reports signs such as a 401-to-200 change, a larger response, or a significant delay.
Why use it?
It checks for authentication bypasses, unwanted data access, and hidden time-based responses that ordinary SQL-injection tools may miss. It compares test requests with a known wrong-credential response to identify suspicious changes.

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

nosqli 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 4d 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.

What it actually says

/nosqli

Test JSON/operator-style NoSQL injection — the "db" attack surface web2 SQLi tools miss. Turns an equality check ({user: X, pass: Y}) into "match anything" via operator injection → auth bypass / data read.

Usage

/nosqli --login https://t/api/login --user-field email --pass-field password
/nosqli --login https://t/api/login --baseline-user [email protected] --baseline-pass wrong
/nosqli --query "https://t/api/items?id=1"

Run directly:

tools/nosqli_scanner.py --login https://t/api/login \
  --user-field email --pass-field password --json

Techniques

Technique Payload Confirms via
Operator auth-bypass {"email":{"$ne":null},"password":{"$ne":null}} response flips 401→200 / body-length jump
Known-user wildcard {"email":"admin","password":{"$ne":""}} same
$regex match-all {"$regex":".*"} same
Bracket-syntax (Express/qs) email[$ne]=&password[$ne]= manual diff (emitted)
$where time-based blind {"$where":"sleep(5000)"} response delay ≥ 3.5s

How detection works

The scanner sends a wrong-credential baseline first, then each payload, and flags a finding when:

  • status flips from 401/403 to 200/302, or
  • body length changes by >25% (or >64 bytes) at the same status, or
  • the $where sleep payload measurably delays the response (server-side JS eval = CRITICAL).

--query mode can't auto-confirm (no baseline), so it prints the bracket- injection variants for you to diff manually in Burp/Repeater.

Impact

Operator auth-bypass on a login = account takeover / full auth bypass (Critical). $where injection = server-side JS execution → often RCE-adjacent.

Changes

What this file has done since we first saw it

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.

nosqli is a command published in the GitHub repository Awarexone/Agentic-Bug-Hunter (4,689 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 529 tokens. 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 2026-08-30.
